### Build Application Bundle

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/struct.Trampoline.html

Builds the application bundle into the specified installation directory. Documentation is available in the OS X build.

```rust
pub fn build(&mut self, dir: InstallDir) -> Result<FruitApp, FruitError>

```

--------------------------------

### Box::from_raw Example

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

Demonstrates recreating a Box from a raw pointer obtained via Box::into_raw. This is crucial for managing memory ownership after converting a Box to a raw pointer.

```rust
let x = Box::new(5);
let ptr = Box::into_raw(x);
let x = unsafe { Box::from_raw(ptr) };

```

--------------------------------

### InstallDir Enum Definition

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/enum.InstallDir.html

Defines the possible locations for saving generated app bundles. Use this enum to specify where your application should be installed or saved.

```rust
pub enum InstallDir {
    Temp,
    SystemApplications,
    UserApplications,
    Custom(String),
}
```

--------------------------------

### Box::into_pin conversion example

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

Illustrates a problematic implementation of From<Box<()>> for Pin<Foo>, which can lead to ambiguity when calling Pin::from. This highlights why such direct conversions are not recommended.

```rust
struct Foo;
impl From<Box<()>> for Pin<Foo> {
    fn from(_: Box<()>) -> Pin<Foo> {
        Pin::new(Foo)
    }
}

let foo = Box::new(());
let bar = Pin::from(foo);
```

--------------------------------

### Box::into_raw Example

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

Shows how to consume a Box and obtain a raw pointer, transferring memory management responsibility to the caller. The pointer can be converted back to a Box for automatic cleanup.

```rust
let x = Box::new(String::from("Hello"));
let ptr = Box::into_raw(x);
let x = unsafe { Box::from_raw(ptr) };

```

--------------------------------

### Box::clone_from_ref Example

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

```rust
#![feature(clone_from_ref)]

let hello: Box<str> = Box::clone_from_ref("hello");
```

--------------------------------

### Box::from_non_null Example (Nightly)

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

Illustrates recreating a Box from a NonNull pointer, typically obtained from Box::into_non_null. This API is experimental and requires the nightly Rust toolchain.

```rust
#![feature(box_vec_non_null)]

let x = Box::new(5);
let non_null = Box::into_non_null(x);
let x = unsafe { Box::from_non_null(non_null) };

```

--------------------------------

### Box::try_clone_from_ref Example

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

Illustrates cloning a value from a reference into a new Box, returning a Result to handle potential allocation errors. This uses the experimental `try_clone_from_ref` function.

```rust
#![feature(clone_from_ref)]
#![feature(allocator_api)]

let hello: Box<str> = Box::try_clone_from_ref("hello")?;
```

--------------------------------

```rust
#![feature(smart_pointer_try_map)]

let b = Box::new(7);
let new = Box::try_map(b, u32::try_from).unwrap();
assert_eq!(*new, 7);
```

--------------------------------

### Get FruitApp Stopper

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/struct.FruitApp.html

Retrieves the stopper for the FruitApp. Documentation is available in the OS X build.

```rust
pub fn stopper(&self) -> FruitStopper
```

--------------------------------

### Box::as_ptr and Box::as_mut_ptr aliasing example

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

Illustrates the interaction between Box::as_ptr and Box::as_mut_ptr, showing that a raw pointer obtained via as_ptr remains valid until a write operation occurs via as_mut_ptr.

```rust
#![feature(box_as_ptr)]

unsafe {
    let mut v = Box::new(0);
    let ptr1 = Box::as_ptr(&v);
    let ptr2 = Box::as_mut_ptr(&mut v);
    let _val = ptr2.read();
    // No write to this memory has happened yet, so `ptr1` is still valid.
    let _val = ptr1.read();
    // However, once we do a write...
    ptr2.write(1);
    // ... `ptr1` is no longer valid.
    // This would be UB: let _val = ptr1.read();
}
```

--------------------------------

### Box::as_mut_ptr aliasing guarantee example

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

Demonstrates the aliasing guarantee of Box::as_mut_ptr, showing that writes to a Box's memory do not invalidate other raw pointers obtained from it, as long as no mutable references are materialized.

```rust
#![feature(box_as_ptr)]

unsafe {
    let mut b = Box::new(0);
    let ptr1 = Box::as_mut_ptr(&mut b);
    ptr1.write(1);
    let ptr2 = Box::as_mut_ptr(&mut b);
    ptr2.write(2);
    // Notably, the write to `ptr2` did *not* invalidate `ptr1`:
    ptr1.write(3);
}
```

--------------------------------

use std::alloc::{Allocator, Layout, System};

unsafe {
    let ptr = System.allocate(Layout::new::<i32>())?.as_mut_ptr() as *mut i32;
    // In general .write is required to avoid attempting to destruct
    // the (uninitialized) previous contents of `ptr`, though for this
    // simple example `*ptr = 5` would have worked as well.
    ptr.write(5);
    let x = Box::from_raw_in(ptr, System);
}

```APIDOC
## Box::try_new

### Description
Allocates memory on the heap then places `x` into it, returning an error if the allocation fails.

```APIDOC
## Function create_logger

### Description
Enable logging to rolling log files with Rust `log` library. This is a helper utility for configuring the Rust `log` and `log4rs` libraries to redirect the `log` macros (`info!()`, `warn!()`, `error!()`, etc) to both stdout and a rotating log file on disk.

    _filename: &str,
    _dir: LogDir,
    _max_size_mb: u32,
    _backup_count: u32,
) -> Result<String, FruitError>
```

### Arguments
* `filename` - Filename for the log file, _without_ path
* `dir` - Directory to save log files in. This is provided as an enum, `LogDir`, which offers some standard logging directories, or allows specification of any custom directory.
* `max_size_mb` - Max size (in megabytes) of the log file before it is rolled into an archive file in the same directory.
* `backup_count` - Number of archived log files to keep before deleting old logs.

### Returns
Full path to opened log file on disk

### Feature Flag
Requires the ‘logging’ feature to be specified at compile time.

### Examples
```rust
#![feature(allocator_api)]

use std::alloc.System;

let zero = Box::<u32, _>::new_zeroed_in(System);
let zero = unsafe { zero.assume_init() };

```

--------------------------------

### pin_in

Source: https://docs.rs/fruitbasket/0.10.0/fruitbasket/type.FruitObjcCallback.html

Constructs a new `Pin<Box<T, A>>`. If `T` does not implement `Unpin`, then `x` will be pinned in memory and unable to be moved.

```APIDOC
## pin_in

### Description
Constructs a new `Pin<Box<T, A>>`. If `T` does not implement `Unpin`, then `x` will be pinned in memory and unable to be moved.

### Signature
`pub fn pin_in<T, A>(x: T, alloc: A) -> Pin<Box<T, A>>`

### Type Parameters
- `T`: The type of the value to be pinned.
- `A`: The type of the allocator, which must implement `Allocator` and have a `'static` lifetime.

### Parameters
- `x` (`T`): The value to be pinned.
- `alloc` (`A`): The allocator to use for memory allocation.

### Returns
- `Pin<Box<T, A>>`: A pinned `Box` containing the value.

### Notes
Constructing and pinning of the `Box` can also be done in two steps: `Box::pin_in(x, alloc)` does the same as `Box::into_pin(Box::new_in(x, alloc))`. Consider using `into_pin` if you already have a `Box<T, A>`, or if you want to construct a (pinned) `Box` in a different way than with `Box::new_in`.

### Examples
```rust
#![feature(allocator_api)]
use std::alloc.System;

let x = Box::pin_in(1, System);
```
```
