Expand description

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

element: Scalar

count: u64

`Aggregate`

Fields

sized: bool

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

Implementations

source

impl Abi

source

pub fn is_unsized(&self) -> bool

source

pub fn is_signed(&self) -> bool

Returns true if this is a single signed integer scalar

source

pub fn is_uninhabited(&self) -> bool

Returns true if this is an uninhabited type

source

pub fn is_scalar(&self) -> bool

Returns true is this is a scalar type
