## What it is
A Rust crate providing the quote! macro for turning Rust syntax tree data structures into token streams of source code. It is primarily used for writing procedural macros but is a general-purpose quasi-quoting library.

## Use cases
- generate Rust code inside a procedural macro
- turn syntax tree data structures back into tokens
- interpolate variables into Rust source code templates
- build custom derive macro implementations
- write code-as-data for metaprogramming

## When to choose
- you are writing Rust procedural macros and need to emit token streams
- you want readable, syntax-highlighted code templates for code generation
- you already use syn and need to convert syntax trees back to tokens

## When to avoid
- you need to parse Rust code rather than generate it (use syn)
- you are generating code in a language other than Rust
- you only need simple string-based code generation without token-level fidelity

## Facets
- artifact type: library
- maturity: stable
- function: parser, developer-tools, compiler
- domain: developer-tools, programming-languages, parsers
- platform: rust
- tags: quasi-quoting, proc-macro, token-stream, metaprogramming, syn
