Enum Output 

#[non_exhaustive]
pub enum Output {
    Stdout,
    Stderr,
    File(PathBuf),
    Both(PathBuf),
}

Where log lines are written.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Stdout

Standard output only. This is the default.

Stderr

Standard error only.

Keeps stdout free for program output, which is what command-line tools usually want. The automatic colour decision checks stderr, not stdout.

File(PathBuf)

The given file only. Created if missing, appended otherwise.

Both(PathBuf)

Both standard output and the given file.

ANSI colours are kept on stdout but stripped from the file, so the on-disk log stays free of escape codes.
