Enum wasmtime::ExternType
source · [−]pub enum ExternType {
Func(FuncType),
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
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.
