Module abi_stable::nonexhaustive_enum

Contains types and traits for nonexhaustive enums.

The most important type here is NonExhaustive, which allows passing an enum which used the #[derive(StableAbi)] #[sabi(kind(WithNonExhaustive(...)))] attributes through ffi.

Structs

DiscrAndEnumInfo	A struct storing the discriminant and EnumInfo of some enum.
EnumInfo	Contains miscelaneous information about an enum.
NonExhaustive	A generic type for all ffi-safe non-exhaustive enums.
UnwrapEnumError	An error for a situation where a NonExhaustive<> could not be unwrapped into the enum because the discriminant wasn't valid in this context (likely because it is from a newer version of the library).

Traits

DeserializeEnum	Describes how a nonexhaustive enum is deserialized.
GetEnumInfo	Describes the discriminant of an enum,and its valid values.
GetNonExhaustive	Gets the type whose type layout is used to represent this enum in NonExhaustive<>.
GetVTable	Gets the vtable of NonExhaustive<Self,S,I>.
NonExhaustiveSharedOps	Used to abstract over the reference-ness of NonExhaustive<> inside UnwrapEnumError.
SerializeEnum	Describes how some enum is serialized.
ValidDiscriminant	Marker trait for types that abi_stable supports as enum discriminants.

Functions

assert_nonexhaustive

Asserts that the size and alignment of an enum are valid for its default storage.
