Crabtime is a Rust crate providing a powerful macro that generates code by evaluating inline Rust logic at compile time. It enables metaprogramming by letting developers write Rust expressions that are evaluated during compilation to produce generated code.

Use cases

• generate Rust code at compile time from inline logic
• evaluate Rust expressions during compilation
• write compile-time metaprogramming without proc macro boilerplate
• compute constants and lookup tables at build time
• replace repetitive macro_rules with inline Rust evaluation

When to choose

• you need compile-time code generation in Rust with plain Rust syntax
• you want simpler alternatives to procedural macros or macro_rules
• you need build-time computed constants or generated functions

When to avoid

• you need runtime code evaluation or dynamic execution
• your project avoids heavy compile-time computation due to build time costs
• you need metaprogramming in a language other than Rust
