proc-macro-kwargs
Keyword argument parsing for function-like procedural macros (Rust).
Example
example_macro!(
name => bar,
foo => i32
);
And here is the corresponding code in the proc macro:
#[derive(MacroKeywordArgs)]
struct MacroArgs {
name: Ident,
#[kwarg(optional)]
optional: Option<syn::Expr>,
#[kwarg(rename = "foo")
tp: Type
}
