A lightweight procedural macro library for extracting string literal contents from tokens, because doing that shouldn't bloat compilation time.

```rust
let value: String = litext!(input);
```

</div>

## What is this?

Litext provides a macro to extract the inner text from a string literal token. You pass raw tokens to `litext!` and it gives you back the unwrapped string content without the quotes, optionally with the source span attached for precise diagnostics.

This is a proc-macro helper library. It is designed for proc-macro authors who need to extract string content from TokenStream input during macro expansion without the bloat.

Zero dependencies, tiny, built for proc-macro authors.

## Installation

Add `litext` to your project:

```sh
cargo add litext
```

## Quick Start

Extract the string content as a `String`:

```rust
use litext::{litext, TokenStream};

pub fn my_macro(input: TokenStream) -> TokenStream {
    let content: String = litext!(input);
    // or, to be explicit:
    let content: String = litext!(input as String);
    // ... use content
}
```

Extract with span information for precise diagnostics:

```rust
use litext::{litext, LitStr, TokenStream};

pub fn my_macro(input: TokenStream) -> TokenStream {
    let lit: LitStr = litext!(input as LitStr);
    let value = lit.value(); // the string content
    let span = lit.span();   // where it appeared in source
    // ... use value and span
}
```

## Features

- Extract string content from `TokenStream` tokens
- Support for regular strings: `"hello world"`
- Support for raw strings: `r#"hello world"#`
- Support for raw strings with multiple hashes: `r##"hello #" world"##`
- Capture source spans via `litext!(input as LitStr)` for precise diagnostics
- Clear error messages for invalid inputs
- Absolutely zero dependencies

## Requirements

- Rust 2024 edition
- A proc-macro crate (this library is for macro authors, not end users)
