enum TtHandle<'tt> {
    TtRef(&'tt TokenTree),
    Token(TokenTree),
}

Variants§

§

TtRef(&'tt TokenTree)

This is used in most cases.

§

Token(TokenTree)

This is only used for implicit token trees. The mbe::TokenTree must be mbe::TokenTree::Token. No other variants are allowed. We store an mbe::TokenTree rather than a Token so that get() can return a &mbe::TokenTree.

source§

impl<'tt> PartialEq<TtHandle<'tt>> for TtHandle<'tt>

source§

fn eq(&self, other: &TtHandle<'tt>) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
