Enum ValueAbi 

pub enum ValueAbi {
    Scalar(Scalar),
    ScalarPair(Scalar, Scalar),
    Vector {
        element: Scalar,
        count: u64,
    },
    Aggregate {
        sized: bool,
    },
}

Describes how values of the type are passed by target ABIs, in terms of categories of C types there are ABI rules for.

Variants

Scalar(Scalar)

ScalarPair(Scalar, Scalar)

Vector

Fields

element: Scalar

count: u64

Aggregate

Fields

sized: bool

If true, the size is exact, otherwise it’s only a lower bound.

Implementations

impl ValueAbi

pub fn is_unsized(&self) -> bool

Returns true if the layout corresponds to an unsized type.

Trait Implementations

impl Clone for ValueAbi

fn clone(&self) -> ValueAbi

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueAbi

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

Formats the value using the given formatter.

impl Hash for ValueAbi

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 ValueAbi

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for ValueAbi

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ValueAbi

impl StructuralPartialEq for ValueAbi

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.
