Enum ExternType

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

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.

§Panics

Panics if self is not of the right type.

Source
