Trait TokenStreamExt

pub trait TokenStreamExt:
    Default
    + Extend<TokenTree>
    + Extend<TokenStream>
    + IntoIterator<Item = TokenTree>
    + Sized {
    // Required method
    fn split_puncts(
        self,
        puncts: impl AsRef<[u8]>,
    ) -> Option<(Self, ParseIter<Self::IntoIter>)>;

    // Provided methods
    fn push(&mut self, tt: TokenTree) -> &mut Self { ... }
    fn add(&mut self, stream: TokenStream) -> &mut Self { ... }
    fn parse_iter(self) -> ParseIter<Self::IntoIter>  { ... }
}

Required Methods

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 parse_iter(self) -> ParseIter<Self::IntoIter>

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.
