Struct syntax::symbol::Symbol

pub struct Symbol(_);

🔬 This is a nightly-only experimental API. (rustc_private)

A symbol is an interned or gensymed string.

Methods

impl Symbol

fn intern(string: &str) -> Self

🔬 This is a nightly-only experimental API. (rustc_private)

Maps a string to its interned representation.

fn gensym(string: &str) -> Self

🔬 This is a nightly-only experimental API. (rustc_private)

gensym's a new usize, using the current interner.

fn as_str(self) -> InternedString

🔬 This is a nightly-only experimental API. (rustc_private)

fn as_u32(self) -> u32

Trait Implementations

impl Clone for Symbol

fn clone(&self) -> Symbol

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Symbol

impl PartialEq for Symbol

fn eq(&self, __arg_0: &Symbol) -> bool
