Enum WasmValue 

Source 
pub enum WasmValue {
    I32(i32),
    I64(i64),
}
Expand description

Value that a Wasm function can accept or produce.

Variants§

§

I32(i32)

A 32-bits integer. There is no fundamental difference between signed and unsigned integer, and the signed-ness should be determined depending on the context.

§

I64(i64)

A 32-bits integer. There is no fundamental difference between signed and unsigned integer, and the signed-ness should be determined depending on the context.
