Enum miri::Scalar

source · [−]

pub enum Scalar<Prov = AllocId> {
    Int(ScalarInt),
    Ptr(Pointer<Prov>, u8),
}

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 an 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

These variants would be private if there was a convenient way to achieve that in Rust. Do not match on a Scalar! Use the various to_* methods instead.

Variants

`Int(ScalarInt)`

The raw bytes of a simple value.

`Ptr(Pointer<Prov>, u8)`

A pointer.

We also store the size of the pointer, such that a Scalar always knows how big it is. The size is always the pointer size of the current target, but this is not information that we always have readily available.
