Implementations§

source§

impl PrimTy

source

pub const ALL: [Self; 17] = _

All of the primitive types

source

pub fn name_str(self) -> &'static str

Like PrimTy::name, but returns a &str instead of a symbol.

Used by clippy.

source

pub fn name(self) -> Symbol

source

pub fn from_name(name: Symbol) -> Option<Self>

Returns the matching PrimTy for a Symbol such as “str” or “i32”. Returns None if no matching type is found.

impl PartialEq<PrimTy> for PrimTy

source§

fn eq(&self, other: &PrimTy) -> 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.
