Enum chalk_ir::TyVariableKind

pub enum TyVariableKind {
    General,
    Integer,
    Float,
}

Represents some extra knowledge we may have about the type variable.

let x: &[u32];
let i = 1;
x[i]

In this example, i is known to be some type of integer. We can infer that it is usize because that is the only integer type that slices have an Index impl for. i would have a TyVariableKind of Integer to guide the inference process.

Trait Implementations

impl Clone for TyVariableKind

fn clone(&self) -> TyVariableKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TyVariableKind

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

Formats the value using the given formatter.

impl Hash for TyVariableKind

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 TyVariableKind

fn eq(&self, other: &TyVariableKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
