Struct cranelift_codegen::ir::immediates::Ieee64

pub struct Ieee64(_);

An IEEE binary64 immediate floating point value, represented as a u64 containing the bit pattern.

All bit patterns are allowed.

Implementations

impl Ieee64

pub fn with_bits(x: u64) -> Self

Create a new Ieee64 containing the bits of x.

pub fn pow2<I: Into<i64>>(n: I) -> Self

Create an Ieee64 number representing 2.0^n.

pub fn fcvt_to_sint_negative_overflow<I: Into<i64>>(n: I) -> Self

Create an Ieee64 number representing the greatest negative value not convertable from f64 to a signed integer with width n.

pub fn neg(self) -> Self

Return self negated.

pub fn with_float(x: f64) -> Self

Create a new Ieee64 representing the number x.

pub fn bits(self) -> u64

Get the bitwise representation.

Trait Implementations

impl Clone for Ieee64

fn clone(&self) -> Ieee64

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ieee64

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

Formats the value using the given formatter.

impl Display for Ieee64

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

Formats the value using the given formatter.

impl FromStr for Ieee64

type Err = &'static str

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, &'static str>

Parses a string s to return a value of this type.

impl Hash for Ieee64

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 PartialEq<Ieee64> for Ieee64

fn eq(&self, other: &Ieee64) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
