Enum TyCategory

pub enum TyCategory {
    Closure,
    Opaque,
    OpaqueFuture,
    Coroutine(CoroutineKind),
    Foreign,
}

This is a bare signal of what kind of type we’re dealing with. ty::TyKind tracks extra information about each type, but we only care about the category.

Implementations

impl TyCategory

pub fn from_ty(tcx: TyCtxt<'_>, ty: Ty<'_>) -> Option<(Self, DefId)>

Trait Implementations

impl Clone for TyCategory

fn clone(&self) -> TyCategory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Display for TyCategory

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

Formats the value using the given formatter.

impl Hash for TyCategory

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TyCategory

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

impl Copy for TyCategory

impl Eq for TyCategory

impl StructuralPartialEq for TyCategory

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.
