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

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.
