Enum wiggle::wasmtime_crate::ExternType

pub enum ExternType {
    Func(FuncType),
    Global(GlobalType),
    Table(TableType),
    Memory(MemoryType),
    Instance(InstanceType),
    Module(ModuleType),
}

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

Func(FuncType)

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.

Instance(InstanceType)

This external type is the type of a WebAssembly instance.

Module(ModuleType)

This external type is the type of a WebAssembly module.

Implementations

impl ExternType

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

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

pub fn unwrap_func(&self) -> &FuncType

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.
