Enum rustc_infer::infer::canonical::CanonicalTyVarKind[−][src]

pub enum CanonicalTyVarKind {
    General(UniverseIndex),
    Int,
    Float,
}

Expand description

Rust actually has more than one category of type variables; notably, the type variables we create for literals (e.g., 22 or 22.) can only be instantiated with integral/float types (e.g., usize or f32). In order to faithfully reproduce a type, we need to know what set of types a given type variable can be unified with.

Variants

General(UniverseIndex)

General type variable ?T that can be unified with arbitrary types.

Tuple Fields of General

0: UniverseIndex

Int

Integral type variable ?I (that can only be unified with integral types).

Float

Floating-point type variable ?F (that can only be unified with float types).
