Struct cranelift_codegen::ir::immediates::Offset32

pub struct Offset32(/* private fields */);

32-bit signed immediate offset.

This is used to encode an immediate offset for load/store instructions. All supported ISAs have a maximum load/store offset that fits in an i32.

Implementations

impl Offset32

pub fn new(x: i32) -> Self

Create a new Offset32 representing the signed number x.

pub fn try_from_i64(x: i64) -> Option<Self>

Create a new Offset32 representing the signed number x if possible.

pub fn try_add_i64(self, x: i64) -> Option<Self>

Add in the signed number x if possible.

Trait Implementations

fn clone(&self) -> Offset32

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Offset32

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

Formats the value using the given formatter.

impl Display for Offset32

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

Formats the value using the given formatter.

impl From<Offset32> for DataValue

fn from(o: Offset32) -> Self

Converts to this type from the input type.

impl From<Offset32> for i32

fn from(val: Offset32) -> i32

Converts to this type from the input type.

impl From<Offset32> for i64

fn from(val: Offset32) -> i64

Converts to this type from the input type.

impl From<i32> for Offset32

fn from(x: i32) -> Self

Converts to this type from the input type.

impl From<u8> for Offset32

fn from(val: u8) -> Offset32

Converts to this type from the input type.

impl FromStr for Offset32

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 Offset32

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<Offset32> for Offset32

fn eq(&self, other: &Offset32) -> 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.
