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
