Represents a canonical function in a WebAssembly component.

Variants

Lift

The function lifts a core WebAssembly function to the canonical ABI.

Fields

core_func_index: u32

The index of the core WebAssembly function to lift.

type_index: u32

The index of the lifted function’s type.

options: Box<[CanonicalOption]>

The canonical options for the function.

Lower

The function lowers a canonical ABI function to a core WebAssembly function.

Fields

func_index: u32

The index of the function to lower.

options: Box<[CanonicalOption]>

The canonical options for the function.

ResourceNew

A function which creates a new owned handle to a resource.

Fields

resource: u32

The type index of the resource that’s being created.

ResourceDrop

A function which is used to drop resource handles of the specified type.

Fields

resource: u32

The type index of the resource that’s being dropped.

ResourceRep

A function which returns the underlying i32-based representation of the specified resource.

Fields

resource: u32

The type index of the resource that’s being accessed.

ThreadSpawn

A function which spawns a new thread by invoking the shared function.

Fields

func_ty_index: u32

The index of the function to spawn.

ThreadHwConcurrency

A function which returns the number of threads that can be expected to execute concurrently

Trait Implementations

impl Clone for CanonicalFunction

fn clone(&self) -> CanonicalFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CanonicalFunction

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

Formats the value using the given formatter.

impl<'a> FromReader<'a> for CanonicalFunction

fn from_reader(reader: &mut BinaryReader<'a>) -> Result<CanonicalFunction>

Attempts to read Self from the provided binary reader, returning an error if it is unable to do so.

impl PartialEq for CanonicalFunction

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