Tuple Fields

0: usize is 0..=HALF_USIZE

Implementations

impl UsizeNoHighBit

pub const fn new(val: usize) -> Option<Self>

🔬This is a nightly-only experimental API. (temporary_niche_types)

pub const unsafe fn new_unchecked(val: usize) -> Self

🔬This is a nightly-only experimental API. (temporary_niche_types)

Constructs an instance of this type from the underlying integer primitive without checking whether its valid.

Safety

Immediate language UB if val is not within the valid range for this type, as it violates the validity invariant.

#[doc(hidden)]

fn assert_fields_are_eq(&self)

🔬This is a nightly-only experimental API. (derive_eq_internals)

impl Hash for UsizeNoHighBit

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H: Hasher>(data: &[Self], state: &mut H)

where Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for UsizeNoHighBit

fn cmp(&self, other: &Self) -> 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,

Restrict a value to a certain interval.

impl PartialEq for UsizeNoHighBit

fn eq(&self, other: &Self) -> 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 UsizeNoHighBit

fn partial_cmp(&self, other: &Self) -> 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.

#[doc(hidden)]

fn __chaining_lt(&self, other: &Rhs) -> ControlFlow<bool>

🔬This is a nightly-only experimental API. (partial_ord_chaining_methods)

If self == other, returns ControlFlow::Continue(()). Otherwise, returns ControlFlow::Break(self < other).

#[doc(hidden)]

fn __chaining_le(&self, other: &Rhs) -> ControlFlow<bool>

🔬This is a nightly-only experimental API. (partial_ord_chaining_methods)

Same as __chaining_lt, but for <= instead of <.

#[doc(hidden)]

fn __chaining_gt(&self, other: &Rhs) -> ControlFlow<bool>

🔬This is a nightly-only experimental API. (partial_ord_chaining_methods)

Same as __chaining_lt, but for > instead of <.

#[doc(hidden)]

fn __chaining_ge(&self, other: &Rhs) -> ControlFlow<bool>

🔬This is a nightly-only experimental API. (partial_ord_chaining_methods)

Same as __chaining_lt, but for >= instead of <.
