Expand description

Information about one scalar component of a Rust type.

Variants§

§

Initialized

Fields

§value: Primitive
§valid_range: WrappingRange
§

Union

Fields

§value: Primitive

Even for unions, we need to use the correct registers for the kind of values inside the union, so we keep the Primitive type around. We also use it to compute the size of the scalar. However, unions never have niches and even allow undef, so there is no valid_range.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
