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.
