rstm

rstm refers to a type of Rust macro that allows for the creation of domain-specific languages (DSLs) and other advanced code generation techniques within the Rust programming language. It is not a built-in feature of Rust itself but rather a popular crate or library that provides powerful tools for macro metaprogramming. The primary goal of rstm is to simplify the process of writing and using complex Rust macros, enabling developers to abstract away repetitive code patterns and define custom syntaxes.

The crate offers a declarative approach to macro definition, making it more accessible than traditional procedural macros for certain use cases. This declarative style often involves defining macro rules and transformations in a structured way, allowing the rstm system to generate the necessary Rust code at compile time. By leveraging rstm, developers can achieve significant reductions in boilerplate code, improve code readability, and enhance the expressiveness of their Rust programs. Its applications range from building embedded DSLs for specific problem domains to generating highly optimized code based on declarative specifications.
