Struct wasmer_c_api::wasm_c_api::value::wasm_val_t

pub kind: wasm_valkind_t,
pub of: wasm_val_inner,
}
Expand description
A WebAssembly value composed of its type and its value.
Note that wasm.h
defines macros to create Wasm values more
easily: WASM_I32_VAL
, WASM_I64_VAL
, WASM_F32_VAL
,
WASM_F64_VAL
, and WASM_REF_VAL
.
Example
int main() {
// Create a 32-bit integer Wasm value.
wasm_val_t value1 = {
.kind = WASM_I32,
.of = { .i32 = 7 },
};
// Create the same value with the `wasm.h` macro.
wasm_val_t value2 = WASM_I32_VAL(7);
assert(value2.kind == WASM_I32);
assert(value1.of.i32 == value2.of.i32);
return 0;
}
Fields§
§kind: wasm_valkind_t
The kind of the value.
of: wasm_val_inner
The real value.
