Expand description
A primitive (aka, builtin) type.
This represents things like i32
, str
, etc.
N.B. This has to be different from hir::PrimTy
because it also includes types that aren’t
paths, like Self::Unit
.

Implementations§
source§impl PrimitiveType
impl PrimitiveType
pub(crate) fn from_hir(prim: PrimTy) -> PrimitiveType
pub(crate) fn from_symbol(s: Symbol) -> Option<PrimitiveType>
pub(crate) fn simplified_types( ) -> &'static FxHashMap<PrimitiveType, ArrayVec<SimplifiedType, 3>>
pub(crate) fn impls<'tcx>( &self, tcx: TyCtxt<'tcx> ) -> impl Iterator<Item = DefId> + 'tcx
pub(crate) fn all_impls(tcx: TyCtxt<'_>) -> impl Iterator<Item = DefId> + '_
pub(crate) fn as_sym(&self) -> Symbol
sourcepub(crate) fn primitive_locations(
tcx: TyCtxt<'_>
) -> &FxHashMap<PrimitiveType, DefId>
pub(crate) fn primitive_locations( tcx: TyCtxt<'_> ) -> &FxHashMap<PrimitiveType, DefId>
Returns the DefId of the module with rustc_doc_primitive
for this primitive type.
Panics if there is no such module.
This gives precedence to primitives defined in the current crate, and deprioritizes
primitives defined in core
,
but otherwise, if multiple crates define the same primitive, there is no guarantee of which
will be picked.
In particular, if a crate depends on both std
and another crate that also defines
rustc_doc_primitive
, then it’s entirely random whether std
or the other crate is picked.
(no_std crates are usually fine unless multiple dependencies define a primitive.)
