Module cranelift_codegen::packed_option
source · Expand description
Compact representation of Option<T> for types with a reserved value.
Small Cranelift types like the 32-bit entity references 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.
