Struct abi_stable::type_layout::LifetimeIndexArray

pub struct LifetimeIndexArray { /* private fields */ }

A LifetimeIndex::NONE terminated array of 5 lifetime indices.

This is represented as 4 bits x 5 inside a u32.

Implementations

impl LifetimeIndexArray

pub const EMPTY: Self = _

An array with no lifetimes.

pub const fn from_array(array: [LifetimeIndex; 5]) -> Self

Constructs this LifetimeIndexArray from an array.

pub const fn to_array(self) -> [LifetimeIndexPair; 3]

Converts this LifetimeIndexArray into an array.

pub const fn to_u20(self) -> u32

Converts this array into its representation.

pub const fn from_u20(bits: u32) -> Self

Constructs this array from its representation.

pub const fn len(self) -> usize

Gets the length of this array.

pub const fn is_empty(self) -> bool

Gets whether the array is empty.

Trait Implementations

impl Clone for LifetimeIndexArray

fn clone(&self) -> LifetimeIndexArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LifetimeIndexArray

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

Formats the value using the given formatter.

impl GetStaticEquivalent_ for LifetimeIndexArray

type StaticEquivalent = _static_LifetimeIndexArray

The 'static equivalent of Self

impl PartialEq for LifetimeIndexArray

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

type IsNonZeroType = <u32 as StableAbi>::IsNonZeroType

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.
