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.

Implementations

source
