Structs§
- Canonical
- A “canonicalized” type
Vis one where all free inference variables have been rewritten to “canonical vars”. These are numbered starting from 0 in order of first appearance. - Canonical
Param EnvCache Entry - Canonical
Query Input - Canonical
VarValues - A set of values corresponding to the canonical variables from some
Canonical. You can give these values tocanonical_value.instantiateto instantiate them into the canonical value at the right places.
Enums§
- Canonical
TyVar Kind - 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.
- Canonical
VarKind - Information about a canonical variable that is included with the canonical value. This is sufficient information for code to create a copy of the canonical value in some other inference context, with fresh inference variables replacing the canonical values.
