Enum ExternType 

pub enum ExternType {
    Function(FunctionType),
    Global(GlobalType),
    Table(TableType),
    Memory(MemoryType),
    Tag(TagType),
}

A list of all possible types which can be externally referenced from a WebAssembly module.

This list can be found in ImportType or ExportType, so these types can either be imported or exported.

Variants

Function(FunctionType)

This external type is the type of a WebAssembly function.

Global(GlobalType)

This external type is the type of a WebAssembly global.

Table(TableType)

This external type is the type of a WebAssembly table.

Memory(MemoryType)

This external type is the type of a WebAssembly memory.

Tag(TagType)

This external type is the type of a WebAssembly tag.

Implementations

impl ExternType

pub fn func(&self) -> Option<&FunctionType>

Attempt to return the underlying type of this external type, returning None if it is a different type.

pub fn unwrap_func(&self) -> &FunctionType

Returns the underlying descriptor of this ExternType, panicking if it is a different type.

Panics

Panics if self is not of the right type.

pub fn global(&self) -> Option<&GlobalType>

Attempt to return the underlying type of this external type, returning None if it is a different type.

pub fn unwrap_global(&self) -> &GlobalType

Returns the underlying descriptor of this ExternType, panicking if it is a different type.

Panics

Panics if self is not of the right type.

pub fn table(&self) -> Option<&TableType>

Attempt to return the underlying type of this external type, returning None if it is a different type.

pub fn unwrap_table(&self) -> &TableType

Returns the underlying descriptor of this ExternType, panicking if it is a different type.

Panics

Panics if self is not of the right type.

pub fn memory(&self) -> Option<&MemoryType>

Attempt to return the underlying type of this external type, returning None if it is a different type.

pub fn unwrap_memory(&self) -> &MemoryType

Returns the underlying descriptor of this ExternType, panicking if it is a different type.

Panics

Panics if self is not of the right type.

pub fn is_compatible_with( &self, other: &ExternType, runtime_size: Option<u32>, ) -> bool

Check if two externs are compatible

Trait Implementations

impl Archive for ExternType

where FunctionType: Archive, GlobalType: Archive, TableType: Archive, MemoryType: Archive, TagType: Archive,

type Archived = ArchivedExternType

The archived representation of this type.

type Resolver = ExternTypeResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <ExternType as Archive>::Resolver, out: Place<<ExternType as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for ExternType

fn clone(&self) -> ExternType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExternType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExternType

fn deserialize<__D>( __deserializer: __D, ) -> Result<ExternType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<ExternType, __D> for <ExternType as Archive>::Archived

where __D: Fallible + ?Sized, FunctionType: Archive, <FunctionType as Archive>::Archived: Deserialize<FunctionType, __D>, GlobalType: Archive, <GlobalType as Archive>::Archived: Deserialize<GlobalType, __D>, TableType: Archive, <TableType as Archive>::Archived: Deserialize<TableType, __D>, MemoryType: Archive, <MemoryType as Archive>::Archived: Deserialize<MemoryType, __D>, TagType: Archive, <TagType as Archive>::Archived: Deserialize<TagType, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<ExternType, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Hash for ExternType

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 ExternType

fn eq(&self, other: &ExternType) -> 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<__S> Serialize<__S> for ExternType

where __S: Fallible + ?Sized, FunctionType: Serialize<__S>, GlobalType: Serialize<__S>, TableType: Serialize<__S>, MemoryType: Serialize<__S>, TagType: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<ExternType as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for ExternType

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ExternType
