Implementations§

Source§

impl FuncKey

Source

pub fn into_parts(self) -> (FuncKeyNamespace, FuncKeyIndex)

Split this key into its namespace and index halves.

Source

pub fn kind(self) -> FuncKeyKind

Get this key’s kind.

Source

pub fn namespace(self) -> FuncKeyNamespace

Get this key’s namespace.

Source

pub fn index(self) -> FuncKeyIndex

Get this key’s index.

Source

pub fn into_raw_parts(self) -> (u32, u32)

Get the raw, underlying (namespace, index) representation of this compilation key.

The resulting values should only be used for (eventually) calling FuncKey::from_raw_parts or FuncKey{Namespace,Index}::from_raw.

Source

pub fn from_parts(namespace: FuncKeyNamespace, index: FuncKeyIndex) -> Self

Create a key from its namespace and index parts.

Should only be called with namespaces and indices that are ultimately derived from the same key. For example, if you attempt to pair an index and namespace that come from different keys, that may panic. If it happens not to panic, you’ll end up with a valid key that names an arbitrary function in the given namespace, but that function probably does not actually exist in the compilation artifact.

Source

pub fn from_raw_parts(a: u32, b: u32) -> Self

Create a key from its raw, underlying representation.

Should only be given the results of a previous call to FuncKey::into_raw_parts.

Panics when given invalid raw parts.

Source

pub fn unwrap_defined_wasm_function( self, ) -> (StaticModuleIndex, DefinedFuncIndex)

Unwrap a FuncKey::DefinedWasmFunction or else panic.

Source

pub fn unwrap_array_to_wasm_trampoline( self, ) -> (StaticModuleIndex, DefinedFuncIndex)

Unwrap a FuncKey::ArrayToWasmTrampoline or else panic.

Source

pub fn unwrap_wasm_to_array_trampoline(self) -> ModuleInternedTypeIndex

Unwrap a FuncKey::WasmToArrayTrampoline or else panic.

Source

pub fn unwrap_wasm_to_builtin_trampoline(self) -> BuiltinFunctionIndex

Unwrap a FuncKey::WasmToBuiltinTrampoline or else panic.

Source

pub fn unwrap_pulley_host_call(self) -> HostCall

Unwrap a FuncKey::PulleyHostCall or else panic.

Source

pub fn unwrap_component_trampoline(self) -> (Abi, TrampolineIndex)

Unwrap a FuncKey::ComponentTrampoline or else panic.

Source

pub fn unwrap_resource_drop_trampoline(self)

Unwrap a FuncKey::ResourceDropTrampoline or else panic.
