Required Methods

fn grouped(self, delimiter: Delimiter) -> Group

Call Group::new

fn split_puncts( self, puncts: impl AsRef<[u8]>, ) -> Option<(Self, ParseIter<Self::IntoIter>)>

Split TokenStream with puncts

Like "+-,-+".split_puncts(",") -> ("+-", "-+")

fn split_puncts_all(self, puncts: impl AsRef<[u8]>) -> Vec<Self>

Split all TokenStream with puncts

Like "+-,-+".split_puncts_all(",") -> "+-", "-+"

Provided Methods

fn push(&mut self, tt: TokenTree) -> &mut Self

Extend a TokenTree

fn add(&mut self, stream: TokenStream) -> &mut Self

Extend a TokenStream

fn take(&mut self) -> Self

Call mem::take

fn grouped_paren(self) -> Group

fn grouped_brace(self) -> Group

fn grouped_bracket(self) -> Group

fn grouped_none(self) -> Group

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
