Enum wasmtime_runtime::TableElement

pub enum TableElement {
    FuncRef(*mut VMFuncRef),
    ExternRef(Option<VMExternRef>),
    UninitFunc,
}

An element going into or coming out of a table.

Table elements are stored as pointers and are default-initialized with ptr::null_mut.

Variants

FuncRef(*mut VMFuncRef)

A funcref.

ExternRef(Option<VMExternRef>)

An exrernref.

UninitFunc

An uninitialized funcref value. This should never be exposed beyond the wasmtime crate boundary; the upper-level code (which has access to the info needed for lazy initialization) will replace it when fetched.
