Struct cranelift_codegen::ir::entities::Constant

pub struct Constant(_);

An opaque reference to a constant

Methods

impl Constant

pub fn from_u32(x: u32) -> Self

Return the underlying index value as a u32.

pub fn as_u32(self) -> u32

Return the underlying index value as a u32.

impl Constant

pub fn with_number(n: u32) -> Option<Self>

Create a const reference from its number.

This method is for use by the parser.

Trait Implementations

impl PartialEq<Constant> for Constant

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for Constant

impl Ord for Constant

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

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

Restrict a value to a certain interval.

impl PartialOrd<Constant> for Constant

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Hash for Constant

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, 

Feeds a slice of this type into the given [Hasher].

impl Display for Constant

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

Formats the value using the given formatter.

impl Debug for Constant

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

Formats the value using the given formatter.

impl Copy for Constant

impl Clone for Constant

fn clone(&self) -> Constant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ReservedValue for Constant

fn reserved_value() -> Constant

Create an instance of the reserved value.

impl EntityRef for Constant

fn new(index: usize) -> Self

Create a new entity reference from a small integer. This should crash if the requested index is not representable.

fn index(self) -> usize

Get the index that was used to create this entity reference.
