Enum UnevaluatedConstKind 

pub enum UnevaluatedConstKind<I: Interner> {
    Projection {
        def_id: I::TraitAssocConstId,
    },
    Inherent {
        def_id: I::InherentAssocConstId,
    },
    Free {
        def_id: I::FreeConstAliasId,
    },
    Anon {
        def_id: I::UnevaluatedConstId,
    },
}

UnevaluatedConstKind is extremely similar to AliasTyKind, and likely should be reasoned about and handled in very similar ways. The documentation for AliasTyKind/etc. may be helpful when learning about UnevaluatedConstKind.

Variants

Projection

A projection <Type as Trait>::AssocConst

Fields

def_id: I::TraitAssocConstId

Inherent

An associated constant in an inherent impl

Fields

def_id: I::InherentAssocConstId

Free

A free constant, outside an impl block.

Fields

def_id: I::FreeConstAliasId

Anon

Anonymous constant, e.g. the 1 + 2 in [u8; 1 + 2].

Fields

def_id: I::UnevaluatedConstId

fn from(value: UnevaluatedConstKind<I>) -> Self

Converts to this type from the input type.

impl<I, J> Lift<J> for UnevaluatedConstKind<I>

where I: Interner, J: Interner, I::TraitAssocConstId: Lift<J, Lifted = J::TraitAssocConstId>, I::InherentAssocConstId: Lift<J, Lifted = J::InherentAssocConstId>, I::FreeConstAliasId: Lift<J, Lifted = J::FreeConstAliasId>, I::UnevaluatedConstId: Lift<J, Lifted = J::UnevaluatedConstId>,

impl<I> PartialEq for UnevaluatedConstKind<I>

where I: Interner,

fn eq(&self, __other: &Self) -> 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<I> Copy for UnevaluatedConstKind<I>

where I: Interner,

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
