Struct ra_ap_proc_macro_api::ProcMacro

source · [−]

pub struct ProcMacro { /* private fields */ }

Expand description

A handle to a specific macro (a #[proc_macro] annotated function).

It exists withing a context of a specific [ProcMacroProcess] – currently we share a single expander process for all macros.
