### Install diff.rs Crate

Source: https://github.com/utkarshkukreti/diff.rs/blob/master/README.md

This snippet shows how to add the `diff` crate as a dependency to your Rust project using Cargo.toml. It specifies version '0.1'.

```toml
[dependencies]
diff = "0.1"
```

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

### Ignore Configuration and Make Files

Source: https://github.com/utkarshkukreti/diff.rs/blob/master/tests/data/gitignores.txt

Ignores project-specific configuration files like config.toml, Makefile, config.mk, and config.stamp. It also ignores a flag indicating no LLVM build.

```gitignore
/config.toml
/Makefile
config.mk
config.stamp
no_llvm_build
```

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

### Ignore Build and Distribution Files

Source: https://github.com/utkarshkukreti/diff.rs/blob/master/tests/data/gitignores.txt

Ignores directories and files generated during the build process, including temporary files (/tmp/, /obj/, *~, #*), output directories (/build/, /dist/, /target/), and documentation (/doc/). This ensures only source code is tracked.

```gitignore
/dl/
/doc/
/inst/
/llvm/
/mingw-build/
/build/
/dist/
/unicode-downloads
/target
/src/tools/x/target
/tmp/
/obj/
*~
#*
#*#
.#*
```

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

### Ignore Pattern Matching Files

Source: https://github.com/utkarshkukreti/diff.rs/blob/master/tests/data/gitignores.txt

This snippet includes patterns for ignoring files that start with '#' or have '#' characters, which might be used for temporary or backup files in some workflows.

```Git Ignore
#*
#*#
```

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

### Ignore Generated Files and IDE Configurations

Source: https://github.com/utkarshkukreti/diff.rs/blob/master/tests/data/gitignores.txt

This snippet covers common ignore patterns for Rust projects, including files generated by the build process (e.g., build artifacts, temporary files), IDE configurations (e.g., VS Code, IntelliJ), and editor swap files.

```Git Ignore
# This file should only ignore things that are generated during a `x.py` build,
# generated by common IDEs, and optional files controlled by the user that
# affect the build (such as config.toml).
# In particular, things like `mir_dump` should not be listed here; they are only
# created during manual debugging and many people like to clean up instead of
# having git ignore such leftovers. You can use `.git/info/exclude` to
# configure your local ignore list.

## File system
.DS_Store
desktop.ini

## Editor
*.swp
*.swo
Session.vim
.cproject
.idea
*.iml
.vscode
.project
.favorites.json
.settings/

## Tool

.cargo
# Included because it is part of the test case
!/src/test/run-make/thumb-none-qemu/example/.cargo

## Configuration
/config.toml
/Makefile
config.mk
config.stamp
no_llvm_build

## Build
/dl/

/inst/
/llvm/
/mingw-build/
/build/
/dist/

/target
/src/tools/x/target
# Generated by compiletest for incremental
/tmp/
# Created by default with `src/ci/docker/run.sh`
/obj/

## Temporary files

### Rust Line Diffing Example

Source: https://github.com/utkarshkukreti/diff.rs/blob/master/README.md

Demonstrates how to use the `diff::lines` function in Rust to compare two multi-line strings. It iterates through the differences, printing lines that were removed, added, or remained the same.

```rust
extern crate diff;

fn main() {
    let left = "foo\nbar\nbaz\nquux";
    let right = "foo\nbaz\nbar\nquux";

    for diff in diff::lines(left, right) {
        match diff {
            diff::Result::Left(l)    => println!("-{}", l),
            diff::Result::Both(l, _) => println!(" {}", l),
            diff::Result::Right(r)   => println!("+{}", r)
        }
    }
}
```

### Rust Build Ignore Patterns
