Enum Lookup 

pub enum Lookup<Value> {
    Unset,
    Found(Value),
    Unhandled,
}

What: The answer of one lookup. Why: “Not set” and “set to this” are Git’s answers; “unhandled” is this module declining to guess, so the caller falls back to starting Git, which is never a failure.

In TS you’d write (pseudocode):

type Lookup<T> = { kind: 'unset' } | { kind: 'found'; value: T } | { kind: 'unhandled' };

Variants

Unset

No entry has the key, so git config --get exits 1.

Found(Value)

The last entry of the key, converted exactly as Git converts it.

Unhandled

Some entry of the key has a shape this module does not reproduce; ask Git.
