Enum stable_mir::abi::Scalar

pub enum Scalar {
    Initialized {
        value: Primitive,
        valid_range: WrappingRange,
    },
    Union {
        value: Primitive,
    },
}

Information about one scalar component of a Rust type.

Variants

Initialized

Fields

value: Primitive

The primitive type used to represent this value.

valid_range: WrappingRange

The range that represents valid values. The range must be valid for the primitive size.

Union

Fields

value: Primitive

Unions never have niches, so there is no valid_range. 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. It is also used to compute the size of the scalar.

Implementations

impl Scalar

pub fn has_niche(&self, target: &MachineInfo) -> bool

Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Scalar

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Scalar

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Scalar

fn eq(&self, other: &Scalar) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Scalar

impl Eq for Scalar

impl StructuralPartialEq for Scalar

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.
