TypeObject

Enum TypeObject 

Source
#[non_exhaustive]
pub enum TypeObject { Minimal(MinimalTypeObject), Complete(CompleteTypeObject), }
Expand description

TypeObject wrapper (Minimal or Complete).

Complete is significantly larger than Minimal (names + annotations per XTypes 1.3 §7.3.1). The wire layout is spec-normative; boxing the Complete variant would reroute ~20 constructor call sites without real memory gain (TypeObject rarely lives on the hot path, but in TypeLookup caches).

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Minimal(MinimalTypeObject)

Minimal representation (hash-exact, nameless).

§

Complete(CompleteTypeObject)

Complete representation (with names + annotations).

Implementations§

Source§

impl TypeObject
