Struct wasmparser::types::TypesRef

pub struct TypesRef<'a> { /* private fields */ }

Represents the types known to a crate::Validator during validation.

Retrieved via the crate::Validator::types method.

Implementations

impl<'a> TypesRef<'a>

pub fn get(&self, id: TypeId) -> Option<&'a Type>

Gets a type based on its type id.

Returns None if the type id is unknown.

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

Gets a core WebAssembly type id from a type index.

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

Panics

This will panic if the index provided is out of bounds.

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

Gets a type id from a type index.

Panics

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

pub fn core_type_count(&self) -> u32

Returns the number of core types defined so far.

pub fn component_type_count(&self) -> u32

Returns the number of component types defined so far.

pub fn table_at(&self, index: u32) -> TableType

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

Panics

This will panic if the index provided is out of bounds.

pub fn table_count(&self) -> u32

Returns the number of tables defined so far.

pub fn memory_at(&self, index: u32) -> MemoryType

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

Panics

Panics

This will panic if the index provided is out of bounds.

pub fn element_count(&self) -> u32

Returns the number of elements defined so far.

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

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

Returns the number of component functions defined so far.

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

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) -> u32

Returns the number of core wasm modules defined so far.

pub fn instance_at(&self, index: u32) -> TypeId

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 instance_count(&self) -> u32

Returns the number of core wasm instances defined so far.

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

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) -> u32

Returns the number of components defined so far.

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

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) -> u32

Returns the number of component instances defined so far.

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