Enum WriteMode 

pub enum WriteMode {
    Truncate,
    Append,
    TruncateBoth,
    AppendBoth,
    Clobber,
}

How an output redirect opens its target. All three land the same bytes somewhere, so they classify identically — the distinction is kept so --explain can echo the command the user actually typed rather than a normalized one. Mutually exclusive by construction: >>| is not a redirect, and a bool pair would let a generator build one.

Variants

Truncate

> — truncate.

Append

>> — append.

TruncateBoth

&> (and the equivalent >&FILE) — stdout AND stderr to the file, truncating. Both streams land on ONE target, so the locus gate has exactly one path to judge, the same as >; the variant exists so --explain echoes the operator that was typed.

AppendBoth

&>> — stdout AND stderr to the file, appending.

Clobber

>| — truncate, overriding noclobber (POSIX 2.7.2).
