Macro syn::braces
[−]
[src]
macro_rules! braces { ($i:expr, $submac:ident!( $($args:tt)* )) => { ... }; ($i:expr, $f:expr) => { ... }; }
Parse inside of {
}
curly braces.
This macro parses a set of balanced braces and invokes a sub-parser on the content inside. The sub-parser is required to consume all tokens within the braces in order for this parser to return successfully.
- Syntax:
braces!(CONTENT)
- Output:
(token::Brace, CONTENT)
#[macro_use] extern crate syn; use syn::Expr; use syn::token::Brace; /// Parses an expression inside of braces. /// /// Example: `{1 + 1}` named!(expr_paren -> (Brace, Expr), braces!(syn!(Expr)));
This macro is available if Syn is built with the "parsing"
feature.
