Enum Width 

pub enum Width {
    W8,
    W16,
    W32,
    W64,
}

An integer width, in the four sizes the machine has instructions for.

Four rather than GCC’s five. mult_init[5] and divide[5] on x86-64 index by mode up to TImode, and rucc lowers 128-bit arithmetic to calls or to pairs of 64-bit operations rather than costing it as one instruction, so a fifth entry would be a number no pass could use honestly.

Variants

W8

One byte.

W16

Two bytes.

W32

Four bytes.

W64

Eight bytes.

Implementations

impl Width

pub const ALL: [Self; 4]

Every width, in order, for a table to be written against.

pub const fn index(self) -> usize

Where this width sits in a width-indexed field.

pub const fn bits(self) -> u32

The width in bits, for a caller that has one and wants the other.

pub const fn from_bits(bits: u32) -> Option<Self>

The width a number of bits names, or nothing for a width the machine has no name for.

Trait Implementations

impl Clone for Width

fn clone(&self) -> Width

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Width

impl Debug for Width

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

Formats the value using the given formatter.

impl Eq for Width

impl Hash for Width

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Width

fn cmp(&self, other: &Width) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for Width

fn eq(&self, other: &Width) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Width

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