I would like to use macros to generate the body of a function, but to do so they need to access variables in the local scope:

Rust macros are hygienic, which prevents identifiers from one scope leaking into another and causing all manner of mayhem. But you can solve this particular problem by passing param from generate_func to generate_body:

Vulnerabilities

No vulnerabilities reported

Install cargo-expand

Install with cargo install cargo-expand. This command optionally uses rustfmt to format the expanded output. The resulting code is typically much more readable than what you get from the compiler. If rustfmt is not available, the expanded code is not formatted. Install rustfmt with rustup component add rustfmt. Cargo expand relies on unstable compiler flags so it requires a nightly toolchain to be installed, though does not require nightly to be the default toolchain or the one with which cargo expand itself is executed. If the default toolchain is one other than nightly, running cargo expand will find and use nightly anyway.
