Struct Types

pub struct Types { /* private fields */ }

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 id(&self) -> ValidatorId

Get the id of the validator that these types are associated with.

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

Gets a reference to this validation type information.

pub fn get<T>(&self, id: T) -> Option<&<T as TypeIdentifier>::Data>

Gets a type based on its type id.

Returns None if the type id is unknown.

pub fn core_type_at(&self, index: u32) -> ComponentCoreTypeId

Panics

Panics if index is not a valid type index.

pub fn core_function_at(&self, index: u32) -> CoreTypeId

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

Panics

Panics if index is not a valid function index.

pub fn core_function_count(&self) -> u32

Gets the count of core functions defined so far.

Note that this includes imported functions, defined functions, and for components lowered/aliased functions.

pub fn element_at(&self, index: u32) -> RefType

Gets the type of an element segment at the given element segment index.

Panics

Gets the count of element segments.

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

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

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

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

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

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

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

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

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

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