Enum Value 

pub enum Value<T> {
    Unset,
    Set(T),
    Bad {
        why: String,
    },
}

What a key said. Three answers, because “unset” is a state this project makes decisions with — amont.commit.gitmoji has four meanings and one of them is absence.

Variants

Unset

Set(T)

Bad

Set to something that could not be read. why is git’s own diagnostic where git produced one, and ours where the constraint is ours (a value outside an allowed set, or outside a range).

Fields

why: String
