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

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

pub(crate) fn primitive_locations(
tcx: TyCtxt<'_>
) -> &FxHashMap<PrimitiveType, DefId>

Returns the DefId of the module with 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 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.)
