Enum rustc_mir::interpret::Scalar[−][src]

pub enum Scalar<Tag = ()> {
    Int(ScalarInt),
    Ptr(Pointer<Tag>),
}

Expand description

A Scalar represents an immediate, primitive value existing outside of a memory::Allocation. It is in many ways like a small chunk of a Allocation, up to 16 bytes in size. Like a range of bytes in an Allocation, a Scalar can either represent the raw bytes of a simple value or a pointer into another Allocation

Variants

Int(ScalarInt)

The raw bytes of a simple value.

Ptr(Pointer<Tag>)

A pointer into an Allocation. An Allocation in the memory module has a list of relocations, but a Scalar is only large enough to contain one, so we just represent the relocation and its associated offset together as a Pointer here.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
