Struct abi_stable::abi_stability::stable_abi_trait::AbiConsts

#[repr(C)]
pub struct AbiConsts {
    pub type_id: Constructor<UTypeId>,
    pub is_nonzero: bool,
}

Contains constants equivalent to the associated types in StableAbi.

Fields

type_id: Constructor<UTypeId>

A function to get the unique identifier for some type

is_nonzero: bool

Whether the type uses non-zero value optimization, if true then an Option<Self> implements StableAbi.

Implementations

impl AbiConsts

pub fn get_type_id(&self) -> UTypeId

Gets the UTypeId returned by the type_id field.

Trait Implementations

impl Clone for AbiConsts

fn clone(&self) -> AbiConsts

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AbiConsts

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

Formats the value using the given formatter.

impl GetStaticEquivalent_ for AbiConsts

type StaticEquivalent = _static_AbiConsts

The 'static equivalent of Self

impl PartialEq for AbiConsts

fn eq(&self, other: &AbiConsts) -> 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 AbiConsts

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.
