Struct wasmer_c_api::wasm_c_api::externals::wasm_extern_vec_t

#[repr(C)]
pub struct wasm_extern_vec_t {
    pub size: usize,
    pub data: *mut Option<Box<wasm_extern_t>>,
}

Represents a vector of wasm_extern_t *.

Read the documentation of [wasm_extern_t *] to see more concrete examples.

Example

void example(wasm_extern_t * x, wasm_extern_t * y) {
    // Create a vector of 2 `wasm_extern_t *`.
    wasm_extern_t * items[2] = {x, y};

    wasm_extern_vec_t vector;
    wasm_extern_vec_new(&vector, 2, items);

    // Check that it contains 2 items.
    assert(vector.size == 2);

    // Free it.
    wasm_extern_vec_delete(&vector);
}

Fields

size: usize

data: *mut Option<Box<wasm_extern_t>>
