Enum ArgumentRewrite 

pub enum ArgumentRewrite {
    Unchanged,
    Rewritten(Vec<OsString>),
}

What: The outcome of one transform. An enum is a closed set of named alternatives; Rewritten carries the new owned argument list, Vec<OsString>. Why: The TypeScript rules returned the same array object to mean “unchanged”; Rust says it with a variant instead of object identity.

In TS you’d write (pseudocode):

type ArgumentRewrite = { kind: 'unchanged' } | { kind: 'rewritten'; args: string[] };

Variants

Unchanged

Forward the caller’s arguments as they are.

Rewritten(Vec<OsString>)

Forward this list instead.
