Enum abi_stable::type_layout::ReprAttr

#[repr(u8)]
pub enum ReprAttr {
    OptionNonZero,
    Primitive,
    C,
    CAndInt(DiscriminantRepr),
    Transparent,
    Int(DiscriminantRepr),
    // some variants omitted
}

The repr(..) attribute used on a type.

Variants

OptionNonZero

This is an Option<NonZeroType>. In which the size and alignment of the Option<_> is exactly that of its contents.

When translated to C,it is equivalent to the type parameter.

Primitive

This is an ffi-safe primitive type,declared in the compiler.

C

A struct whose fields are laid out like C,

CAndInt(DiscriminantRepr)

An enum with a #[repr(C, IntegerType)] attribute.

Transparent

A type with the same size,alignment and function ABI as its only non-zero-sized field.

Int(DiscriminantRepr)

Means that only repr(IntegerType) was used.

Trait Implementations

impl Clone for ReprAttr

fn clone(&self) -> ReprAttr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReprAttr

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

Formats the value using the given formatter.

impl GetStaticEquivalent_ for ReprAttr

type StaticEquivalent = _static_ReprAttr

The 'static equivalent of Self

impl PartialEq for ReprAttr

fn eq(&self, other: &ReprAttr) -> 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 StableAbi for ReprAttr

type IsNonZeroType = False

Whether this type has a single invalid bit-pattern.

const LAYOUT: &'static TypeLayout = _

The layout of the type provided by implementors.

const ABI_CONSTS: AbiConsts = _

const-equivalents of the associated types.
