Enum 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

UninhabitedScalar(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.

Methods

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

Trait Implementations

impl PartialEq<Abi> for Abi

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

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

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

This method tests for !=.

impl Clone for Abi

fn clone(&self) -> Abi

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for Abi

impl Debug for Abi

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

Formats the value using the given formatter.

impl Hash for Abi

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, 

Feeds a slice of this type into the given [Hasher].
