Implementations

impl LifetimeRange

pub const EMPTY: Self = _

pub const MAX_START: usize = 8_191usize

The maximum value for the start of a range.

pub const MAX_LEN: usize = 127usize

The maximum length of a range.

pub const fn Param(index: u8) -> Self

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

Constructs a LifetimeRange from an array of 5 lifetime indices.

pub const fn from_range(range: Range<usize>) -> Self

Constructs a LifetimeRange from a range.

pub const fn len(self) -> usize

The amount of lifetime indices this spans.

pub const fn is_empty(self) -> bool

Whether this span of lifetimes is empty.

pub const fn is_range(self) -> bool

Whether this is a range into a slice of LifetimePairs.

pub const fn to_u21(self) -> u32

Converts this LifetimeRange into its representation

pub const fn from_u21(bits: u32) -> Self

Constructs this LifetimeRange from its representation

impl LifetimeRange

pub fn slicing( self, lifetime_indices: &[LifetimeIndexPair], ) -> LifetimeArrayOrSlice<'_>

Expands this LifetimeRange into a LifetimeArrayOrSlice

Trait Implementations

impl Clone for LifetimeRange

fn clone(&self) -> LifetimeRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LifetimeRange

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

Formats the value using the given formatter.

impl GetStaticEquivalent_ for LifetimeRange

type StaticEquivalent = _static_LifetimeRange

The 'static equivalent of Self

impl Ord for LifetimeRange

fn cmp(&self, other: &LifetimeRange) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for LifetimeRange

fn eq(&self, other: &LifetimeRange) -> 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 PartialOrd for LifetimeRange

fn partial_cmp(&self, other: &LifetimeRange) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StableAbi for LifetimeRange

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.
