Module wasmer_types::entity::packed_option

Compact representation of Option<T> for types with a reserved value.

Small types are often used in tables and linked lists where an Option<T> is needed. Unfortunately, that would double the size of the tables because Option<T> is twice as big as T.

This module provides a PackedOption<T> for types that have a reserved value that can be used to represent None.

Structs

• PackedOption
  Packed representation of Option<T>.

Traits
