Struct wasmtime_runtime::I31

pub struct I31(/* private fields */);

A 31-bit integer for use with i31ref.

Implementations

impl I31

pub fn new_u32(value: u32) -> Option<Self>

Construct a new I31 from the given unsigned value.

Returns None if the value does not fit in the bottom 31 bits.

pub fn new_i32(value: i32) -> Option<Self>

Construct a new I31 from the given signed value.

Returns None if the value does not fit in the bottom 31 bits.

pub fn wrapping_u32(value: u32) -> Self

Construct a new I31 from the given unsigned value.

If the value doesn’t fit in the bottom 31 bits, it is wrapped such that the wrapped value does.

pub fn wrapping_i32(value: i32) -> Self

Construct a new I31 from the given signed value.

If the value doesn’t fit in the bottom 31 bits, it is wrapped such that the wrapped value does.

pub fn get_u32(&self) -> u32

Get this I31’s value as an unsigned integer.

pub fn get_i32(&self) -> i32

Get this I31’s value as ansigned integer.

Trait Implementations

impl Clone for I31

fn clone(&self) -> I31

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for I31

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

Formats the value using the given formatter.

impl Default for I31

fn default() -> Self

Returns the “default value” for a type.

impl Hash for I31

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 for I31

fn eq(&self, other: &I31) -> 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.
