Struct syn::buffer::TokenBuffer

pub struct TokenBuffer { /* fields omitted */ }

A buffer that can be efficiently traversed multiple times, unlike TokenStream which requires a deep copy in order to traverse more than once.

See the module documentation for an example of TokenBuffer in action.

This type is available if Syn is built with the "parsing" feature.

Methods

impl TokenBuffer

pub fn new(stream: TokenStream) -> TokenBuffer

Creates a TokenBuffer containing all the tokens from the input TokenStream.

This method is available if Syn is built with both the "parsing" and "proc-macro" features.

pub fn new2(stream: TokenStream) -> TokenBuffer

Creates a TokenBuffer containing all the tokens from the input TokenStream.

pub fn begin(&self) -> Cursor

Creates a cursor referencing the first token in the buffer and able to traverse until the end of the buffer.
