Struct `TokenBuffer`

struct TokenBuffer { ... }

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

Implementations

fn new(stream: proc_macro::TokenStream) -> Self: Creates a TokenBuffer containing all the tokens from the input proc_macro::TokenStream.
fn new2(stream: TokenStream) -> Self: Creates a TokenBuffer containing all the tokens from the input proc_macro2::TokenStream.
fn begin(self: &Self) -> Cursor<'_>: Creates a cursor referencing the first token in the buffer and able to traverse until the end of the buffer.

fn into(self: Self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of [From]<T> for U chooses to do.
