Struct Types 

pub struct Types { /* private fields */ }

Available on crate feature validate only.

Represents the types known to a crate::Validator once validation has completed.

The type information is returned via the crate::Validator::end method.

Implementations

impl Types

pub fn component_any_type_at(&self, index: u32) -> ComponentAnyTypeId

Available on crate feature component-model only.

Gets a component WebAssembly type at the given type index.

Note that this is in contrast to TypesRef::core_type_at_in_component which gets a core type from its index.

Panics

Panics if index is not a valid type index.

pub fn component_type_at(&self, index: u32) -> ComponentTypeId

Available on crate feature component-model only.

Gets a component type at the given type index.

Panics

Panics if index is not a valid component type index.

pub fn component_defined_type_at(&self, index: u32) -> ComponentDefinedTypeId

Available on crate feature component-model only.

Gets a component type from the given component type index.

Panics

Panics if index is not a valid defined type index or if this type information represents a core module.

pub fn component_function_at(&self, index: u32) -> ComponentFuncTypeId

Available on crate feature component-model only.

Gets the type of a component function at the given function index.

Panics

This will panic if the index provided is out of bounds or if this type information represents a core module.

pub fn component_function_count(&self) -> u32

Available on crate feature component-model only.

Gets the count of imported, exported, or aliased component functions.

pub fn module_at(&self, index: u32) -> ComponentCoreModuleTypeId

Available on crate feature component-model only.

Gets the type of a module at the given module index.

Panics

This will panic if the index provided is out of bounds or if this type information represents a core module.

pub fn module_count(&self) -> usize

Available on crate feature component-model only.

Gets the count of imported, exported, or aliased modules.

pub fn core_instance_at(&self, index: u32) -> ComponentCoreInstanceTypeId

Available on crate feature component-model only.

Gets the type of a module instance at the given module instance index.

Panics

This will panic if the index provided is out of bounds or if this type information represents a core module.

pub fn core_instance_count(&self) -> usize

Available on crate feature component-model only.

Gets the count of imported, exported, or aliased core module instances.

pub fn component_at(&self, index: u32) -> ComponentTypeId

Available on crate feature component-model only.

Gets the type of a component at the given component index.

Panics

This will panic if the index provided is out of bounds or if this type information represents a core module.

pub fn component_count(&self) -> usize

Available on crate feature component-model only.

Gets the count of imported, exported, or aliased components.

pub fn component_instance_at(&self, index: u32) -> ComponentInstanceTypeId

Available on crate feature component-model only.

Gets the type of an component instance at the given component instance index.

Panics

This will panic if the index provided is out of bounds or if this type information represents a core module.

pub fn component_instance_count(&self) -> usize

Available on crate feature component-model only.

Gets the count of imported, exported, or aliased component instances.

pub fn value_at(&self, index: u32) -> ComponentValType

Available on crate feature component-model only.

Gets the type of a value at the given value index.

Panics

This will panic if the index provided is out of bounds or if this type information represents a core module.

pub fn value_count(&self) -> usize

Available on crate feature component-model only.

Gets the count of imported, exported, or aliased values.

pub fn component_item_for_import(&self, name: &str) -> Option<&ComponentItem>

Available on crate feature component-model only.

Gets the component entity type for the given component import name.

pub fn component_item_for_export(&self, name: &str) -> Option<&ComponentItem>

Available on crate feature component-model only.

Gets the component entity type for the given component export name.

pub fn peel_alias<T>(&self, ty: T) -> Option<T>

where T: Aliasable,

Available on crate feature component-model only.

Attempts to lookup the type id that ty is an alias of.

Returns None if ty wasn’t listed as aliasing a prior type.

impl Types

pub fn as_ref(&self) -> TypesRef<'_>

Return a TypesRef through which types can be inspected.

Trait Implementations

impl<T> Index<T> for Types

where T: TypeIdentifier,

type Output = <T as TypeIdentifier>::Data

The returned type after indexing.

fn index(&self, id: T) -> &Self::Output

Performs the indexing (container[index]) operation.
