### Example: Handling IO Error Kind

Source: https://docs.rs/fhirbolt/latest/fhirbolt/serde/json/error/struct.Error.html

Demonstrates how to check for specific IO error kinds, such as 'TimedOut', when deserializing JSON. This is useful for implementing retry logic.

```rust
use serde_json::Value;
use std::io::{self, ErrorKind, Read};
use std::process;

struct ReaderThatWillTimeOut<'a>(&'a [u8]);

impl<'a> Read for ReaderThatWillTimeOut<'a> {
    fn read(&mut self, buf: &mut [u8]) -> io::Result<usize> {
        if self.0.is_empty() {
            Err(io::Error::new(ErrorKind::TimedOut, "timed out"))
        } else {
            self.0.read(buf)
        }
    }
}

fn main() {
    let reader = ReaderThatWillTimeOut(br#" {"k": "#);

    let _: Value = match serde_json::from_reader(reader) {
        Ok(value) => value,
        Err(error) => {
            if error.io_error_kind() == Some(ErrorKind::TimedOut) {
                // Maybe this application needs to retry certain kinds of errors.

            } else {
                eprintln!("error: {}", error);
                process::exit(1);
            }
        }
    };
}
```

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

### Rust TryInto Trait Example

Source: https://docs.rs/fhirbolt/latest/fhirbolt/model/r5/resources/struct.SubstanceSourceMaterialOrganismHybrid.html

Demonstrates the `TryInto` trait, the fallible counterpart to `Into`. It returns a `Result` and uses the error type defined by the corresponding `TryFrom` implementation.

```rust
type Error = <U as TryFrom<T>>::Error;

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>
where U: TryFrom<T>
```

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

### Unchecked Err Value Access

Source: https://docs.rs/fhirbolt/latest/fhirbolt/serde/element/type.Result.html

Use `unwrap_err_unchecked()` to get the Err value without checking for Ok. This is unsafe and can lead to undefined behavior if called on an Ok.

```rust
let x: Result<u32, &str> = Ok(2);
unsafe { x.unwrap_err_unchecked() }; // Undefined behavior!
```

```rust
let x: Result<u32, &str> = Err("emergency failure");
assert_eq!(unsafe { x.unwrap_err_unchecked() }, "emergency failure");
```

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

### Unchecked Ok Value Access

Source: https://docs.rs/fhirbolt/latest/fhirbolt/serde/element/type.Result.html

Use `unwrap_unchecked()` to get the Ok value without checking for Err. This is unsafe and can lead to undefined behavior if called on an Err.

```rust
let x: Result<u32, &str> = Ok(2);
assert_eq!(unsafe { x.unwrap_unchecked() }, 2);
```

```rust
let x: Result<u32, &str> = Err("emergency failure");
unsafe { x.unwrap_unchecked(); } // Undefined behavior!
```

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

### CloneToUninit Implementation (Nightly)

Source: https://docs.rs/fhirbolt/latest/fhirbolt/model/r5/resources/struct.ClinicalUseDefinitionIndication.html

Performs copy-assignment from self to a raw pointer destination. This is a nightly-only experimental API.

```rust
unsafe fn clone_to_uninit(&self, dest: *mut u8)
where T: Clone,
```

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

### PartialEq Trait Implementation for ExampleScenarioInstance

Source: https://docs.rs/fhirbolt/latest/fhirbolt/model/r5/resources/struct.ExampleScenarioInstance.html

Enables equality comparison between two ExampleScenarioInstance instances.

```rust
impl PartialEq for ExampleScenarioInstance
fn eq(&self, other: &ExampleScenarioInstance) -> bool
const fn ne(&self, other: &Rhs) -> bool
```

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

    pub modifier_extension: Vec<Extension>,
    pub category: Option<Box<CodeableConcept>>,
