Struct wasmtime_environ::ModuleTypes

pub struct ModuleTypes { /* private fields */ }

All types used in a core wasm module.

At this time this only contains function types. Note, though, that function types are deduplicated within this ModuleTypes.

Note that accesing this type is primarily done through the Index implementations for this type.

Implementations

impl ModuleTypes

pub fn wasm_types( &self ) -> impl ExactSizeIterator<Item = (ModuleInternedTypeIndex, &WasmSubType)>

Returns an iterator over all the wasm function signatures found within this module.

pub fn get(&self, ty: ModuleInternedTypeIndex) -> Option<&WasmSubType>

Get the type at the specified index, if it exists.

pub fn rec_groups( &self ) -> impl ExactSizeIterator<Item = (ModuleInternedRecGroupIndex, Range<ModuleInternedTypeIndex>)> + '_

Get an iterator over all recursion groups defined in this module and their elements.

pub fn rec_group_elements( &self, rec_group: ModuleInternedRecGroupIndex ) -> impl ExactSizeIterator<Item = ModuleInternedTypeIndex>

Get the elements within an already-defined rec group.

pub fn len_types(&self) -> usize

Returns the number of types interned.

pub fn push(&mut self, ty: WasmSubType) -> ModuleInternedTypeIndex

Adds a new type to this interned list of types.

pub fn push_rec_group( &mut self, range: Range<ModuleInternedTypeIndex> ) -> ModuleInternedRecGroupIndex

Adds a new rec group to this interned list of types.

pub fn reserve(&mut self, amt: usize)

Reserves space for amt more types.

pub fn next_rec_group(&self) -> ModuleInternedRecGroupIndex

Returns the next return value of push_rec_group.

pub fn next_ty(&self) -> ModuleInternedTypeIndex

Returns the next return value of push.

Trait Implementations

impl Default for ModuleTypes

fn default() -> ModuleTypes

impl<'de> Deserialize<'de> for ModuleTypes

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl Index<ModuleInternedTypeIndex> for ModuleTypes

type Output = WasmSubType

The returned type after indexing.

fn index(&self, sig: ModuleInternedTypeIndex) -> &WasmSubType

Performs the indexing (container[index]) operation.
