Struct cranelift_codegen::ir::immediates::Imm64

pub struct Imm64(/* private fields */);

64-bit immediate signed integer operand.

An Imm64 operand can also be used to represent immediate values of smaller integer types by sign-extending to i64.

Implementations

impl Imm64

pub fn new(x: i64) -> Self

Create a new Imm64 representing the signed number x.

pub fn wrapping_neg(self) -> Self

Return self negated.

pub fn bits(&self) -> i64

Returns the value of this immediate.

pub fn sign_extend_from_width(&mut self, bit_width: u32)

Sign extend this immediate as if it were a signed integer of the given power-of-two width.

Trait Implementations

impl Clone for Imm64

fn clone(&self) -> Imm64

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Imm64

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

Formats the value using the given formatter.

impl Display for Imm64

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

Formats the value using the given formatter.

impl From<Imm64> for i64

fn from(val: Imm64) -> i64

Converts to this type from the input type.

impl From<i64> for Imm64

fn from(x: i64) -> Self

Converts to this type from the input type.

impl FromStr for Imm64

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 Imm64

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 IntoBytes for Imm64

fn into_bytes(self) -> Vec<u8>

Return the little-endian byte representation of the implementing type.

impl PartialEq for Imm64

fn eq(&self, other: &Imm64) -> 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.
