rust: error: optimize error type to use nonzero
Optimize `Result<(), Error>` size by changing `Error` type to
`NonZero*` for niche optimization.
This reduces the space used by the `Result` type, as the `NonZero*`
type enables the compiler to apply more efficient memory layout.
For example, the `Result<(), Error>` changes size from 8 to 4 bytes.
