Struct wasmtime::V128

pub struct V128(/* private fields */);

Available on crate feature runtime only.

Representation of a 128-bit vector type, v128, for WebAssembly.

This type corresponds to the v128 type in WebAssembly and can be used with the TypedFunc API for example. This is additionally the payload of Val::V128.

Platform specifics

This type can currently only be used on x86_64 and AArch64 with the TypedFunc API. Rust does not have stable support on other platforms for this type so invoking functions with v128 parameters requires the Func::call API (or perhaps Func::call_unchecked.

Implementations

impl V128

pub fn as_u128(&self) -> u128

Returns the representation of this v128 as a 128-bit integer in Rust.

Trait Implementations

impl Clone for V128

fn clone(&self) -> V128

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for V128

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

Formats the value using the given formatter.

impl From<V128> for Val

fn from(val: V128) -> Val

Converts to this type from the input type.

impl From<V128> for u128

fn from(val: V128) -> u128

Converts to this type from the input type.

impl From<u128> for V128

Primary constructor of a V128 type.

fn from(val: u128) -> V128

Converts to this type from the input type.

impl Ord for V128

fn cmp(&self, other: &V128) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for V128

fn eq(&self, other: &V128) -> 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.

impl PartialOrd for V128

fn partial_cmp(&self, other: &V128) -> Option<Ordering>

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

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

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

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

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

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

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

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

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