Enum 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)

Available on crate feature validate only.

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

Available on crate feature validate only.

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>

Available on crate feature validate only.

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

Formats the value using the given formatter.

impl Display for UnpackedIndex

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

Formats the value using the given formatter.

impl Hash for UnpackedIndex

fn hash<__H: Hasher>(&self, state: &mut __H)

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 Ord for UnpackedIndex

fn cmp(&self, other: &UnpackedIndex) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for UnpackedIndex

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for UnpackedIndex

fn partial_cmp(&self, other: &UnpackedIndex) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
