version.ReleaseSuffix.release_candidate(number: u16) -> Option<Self>
```

Construct a numbered release-candidate suffix.

Candidate one displays canonically as `-rc`. Zero is not a valid
release-candidate number.

## Example

```rust
use libtmux::ReleaseSuffix;

let suffix = ReleaseSuffix::release_candidate(2).expect("two is nonzero");
assert_eq!(suffix.release_candidate_number(), Some(2));
assert_eq!(ReleaseSuffix::release_candidate(0), None);
```
