Enum rustc_expand::mbe::macro_parser::TokenTreeOrTokenTreeSlice

enum TokenTreeOrTokenTreeSlice<'tt> {
    Tt(TokenTree),
    TtSeq(&'tt [TokenTree]),
}

Either a sequence of token trees or a single one. This is used as the representation of the sequence of tokens that make up a matcher.

Variants

Tt(TokenTree)

TtSeq(&'tt [TokenTree])

Implementations

impl<'tt> TokenTreeOrTokenTreeSlice<'tt>

fn len(&self) -> usize

Returns the number of constituent top-level token trees of self (top-level in that it will not recursively descend into subtrees).

fn get_tt(&self, index: usize) -> TokenTree

The index-th token tree of self.

Trait Implementations

impl<'tt> Clone for TokenTreeOrTokenTreeSlice<'tt>

fn clone(&self) -> TokenTreeOrTokenTreeSlice<'tt>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
