Enum wasmtime_environ::EngineOrModuleTypeIndex

pub enum EngineOrModuleTypeIndex {
    Engine(u32),
    Module(ModuleInternedTypeIndex),
}

An interned type index, either at the module or engine level.

Roughly equivalent to wasmparser::UnpackedIndex, although doesn’t have to concern itself with recursion-group-local indices.

Variants

Engine(u32)

An index within a global namespace across all modules that can interact with each other (in practice this is a VMSharedTypeIndex at the per wasmtime::Engine level).

Module(ModuleInternedTypeIndex)

An index within the current Wasm module.

Implementations

impl EngineOrModuleTypeIndex

pub fn is_engine_type_index(self) -> bool

Is this an engine-level type index?

pub fn as_engine_type_index(self) -> Option<u32>

Get the underlying engine-level type index, if any.

pub fn unwrap_engine_type_index(self) -> u32

Get the underlying engine-level type index, or panic.

pub fn is_module_type_index(self) -> bool

Is this an module-level type index?

pub fn as_module_type_index(self) -> Option<ModuleInternedTypeIndex>

Get the underlying module-level type index, if any.

pub fn unwrap_module_type_index(self) -> ModuleInternedTypeIndex

Get the underlying module-level type index, or panic.

Trait Implementations

impl Clone for EngineOrModuleTypeIndex

fn clone(&self) -> EngineOrModuleTypeIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EngineOrModuleTypeIndex

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EngineOrModuleTypeIndex

fn deserialize<__D>( __deserializer: __D ) -> Result<EngineOrModuleTypeIndex, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EngineOrModuleTypeIndex

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

Formats the value using the given formatter.

impl From<ModuleInternedTypeIndex> for EngineOrModuleTypeIndex

fn from(i: ModuleInternedTypeIndex) -> EngineOrModuleTypeIndex

Converts to this type from the input type.

impl Hash for EngineOrModuleTypeIndex

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 EngineOrModuleTypeIndex

fn eq(&self, other: &EngineOrModuleTypeIndex) -> 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 Serialize for EngineOrModuleTypeIndex

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
