Struct syn::buffer::TokenBuffer[][src]

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.

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

Implementations

impl TokenBuffer[src]

pub fn new(stream: TokenStream) -> TokenBuffer[src]

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

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

pub fn new2(stream: TokenStream) -> TokenBuffer[src]

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

pub fn begin(&self) -> Cursor<'_>[src]

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