Struct wasmer_runtime_c_api::value::wasmer_value_t

#[repr(C)]
pub struct wasmer_value_t {
    pub tag: wasmer_value_tag,
    pub value: wasmer_value,
}

Represents a WebAssembly type and value pair, i.e. wasmer_value_tag and wasmer_value. Since the latter is an union, it's the safe way to read or write a WebAssembly value in C.

Example:

// Create a WebAssembly value.
wasmer_value_t wasm_value = {
    .tag = WASM_I32,
    .value.I32 = 42,
};

// Read a WebAssembly value.
if (wasm_value.tag == WASM_I32) {
    int32_t x = wasm_value.value.I32;
    // …
}

Fields

tag: wasmer_value_tag

The value type.

value: wasmer_value

The value.
