Enum WasmType

pub enum WasmType {
    I32,
    I64,
    F32,
    F64,
    Pointer,
    PointerOrI64,
    Length,
}

Enumerates wasm types used by interface types when lowering/lifting.

Variants

I32

I64

F32

F64

Pointer

A pointer type. In core Wasm this typically lowers to either i32 or i64 depending on the index type of the exported linear memory, however bindings can use different source-level types to preserve provenance.

Users that don’t do anything special for pointers can treat this as i32.

PointerOrI64

A type for values which can be either pointers or 64-bit integers. This occurs in variants, when pointers and non-pointers are unified.

Users that don’t do anything special for pointers can treat this as i64.

Length

An array length type. In core Wasm this lowers to either i32 or i64 depending on the index type of the exported linear memory.

Users that don’t do anything special for pointers can treat this as i32.

Trait Implementations

impl Clone for WasmType

fn clone(&self) -> WasmType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WasmType

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

Formats the value using the given formatter.

impl From<Int> for WasmType

fn from(i: Int) -> WasmType

Converts to this type from the input type.

impl Hash for WasmType

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 Ord for WasmType

fn cmp(&self, other: &WasmType) -> 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,

Restrict a value to a certain interval.

impl PartialEq for WasmType

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for WasmType

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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