Enum wasmtime_environ::wasmparser::UnpackedIndex

pub enum UnpackedIndex {
    Module(u32),
    RecGroup(u32),
    Id(CoreTypeId),
}

The uncompressed form of a PackedIndex.

Can be used for match statements.

Variants

Module(u32)

An index into a Wasm module’s types space.

RecGroup(u32)

An index into the containing recursion group’s elements.

Id(CoreTypeId)

A type identifier.

Implementations

impl UnpackedIndex

pub fn pack(&self) -> Option<PackedIndex>

Compress this index into its packed form.

Returns None if an index is beyond implementation limits.

pub fn is_canonical(&self) -> bool

Is this index in canonical form?

pub fn as_module_index(&self) -> Option<u32>

Get the underlying index into a module’s types space, if any.

pub fn as_rec_group_index(&self) -> Option<u32>

Get the underlying index into the containing recursion group, if any.

pub fn as_core_type_id(&self) -> Option<CoreTypeId>

Get the underlying CoreTypeId, if any.

Trait Implementations

impl Clone for UnpackedIndex

fn clone(&self) -> UnpackedIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnpackedIndex

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

Formats the value using the given formatter.

impl Display for UnpackedIndex

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

Formats the value using the given formatter.

impl Hash for UnpackedIndex

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 UnpackedIndex

fn eq(&self, other: &UnpackedIndex) -> 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.
