Macro syn::bracketed [−][src]
Parse a set of square brackets and expose their content to subsequent parsers.
Example
use proc_macro2::TokenStream; use syn::{bracketed, token, Result, Token}; use syn::parse::{Parse, ParseStream}; // Parse an outer attribute like: // // #[repr(C, packed)] struct OuterAttribute { pound_token: Token![#], bracket_token: token::Bracket, content: TokenStream, } impl Parse for OuterAttribute { fn parse(input: ParseStream) -> Result<Self> { let content; Ok(OuterAttribute { pound_token: input.parse()?, bracket_token: bracketed!(content in input), content: content.parse()?, }) } }
