Enum TtHandle

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.

Implementations

impl<'tt> TtHandle<'tt>

fn from_token(tok: Token) -> Self

fn from_token_kind(kind: TokenKind, span: Span) -> Self

fn get(&'tt self) -> &'tt TokenTree

Trait Implementations

impl<'tt> Clone for TtHandle<'tt>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tt> Debug for TtHandle<'tt>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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

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

Tests for self and other values to be equal, and is used by ==.

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

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

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.
