Variants

Func

Untyped (any) function.

Extern

External heap type.

Any

The any heap type. The common supertype (a.k.a. top) of all internal types.

None

The none heap type. The common subtype (a.k.a. bottom) of all internal types.

NoExtern

The noextern heap type. The common subtype (a.k.a. bottom) of all external types.

NoFunc

The nofunc heap type. The common subtype (a.k.a. bottom) of all function types.

Eq

The eq heap type. The common supertype of all referenceable types on which comparison (ref.eq) is allowed.

Struct

The struct heap type. The common supertype of all struct types.

Array

The array heap type. The common supertype of all array types.

I31

The i31 heap type.

Indexed(u32)

User defined type at the given index.

Trait Implementations

impl Clone for HeapType

fn clone(&self) -> HeapType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeapType

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

Formats the value using the given formatter.

impl Encode for HeapType

fn encode(&self, sink: &mut Vec<u8>)

Encode the type into the given byte sink.

impl Hash for HeapType

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 HeapType

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<HeapType> for HeapType

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

impl PartialOrd<HeapType> for HeapType

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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