Enum wasmer_types::ExternType

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

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.

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: &Self) -> bool

Check if two externs are compatible
