Enum rustc_ap_rustc_target::abi::Abi

pub enum Abi {
    Uninhabited,
    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

Uninhabited

Scalar(Scalar)

ScalarPair(Scalar, Scalar)

Vector

Fields of Vector

element: Scalarcount: u64

Aggregate

Fields of Aggregate

sized: bool

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

Implementations

impl Abi

pub fn is_unsized(&self) -> bool

Returns true if the layout corresponds to an unsized type.

pub fn is_signed(&self) -> bool

Returns true if this is a single signed integer scalar

pub fn is_uninhabited(&self) -> bool

Returns true if this is an uninhabited type

pub fn is_scalar(&self) -> bool

Returns true is this is a scalar type

Trait Implementations

impl Clone for Abi

fn clone(&self) -> Abi
