Trait TokenStreamExt

pub trait TokenStreamExt:

}

Required Methods

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

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

Split TokenStream to predicate false and true

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

Provided Methods

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

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

fn walk<F>(self, f: F) -> Self

where F: FnMut(TokenTree) -> TokenTree,

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.
