# 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.
