Enum CommandError 

pub enum CommandError {
    NotFound(String),
    Unhandled(String),
    Failed(String),
}

Variants

NotFound(String)

Unhandled(String)

A registered command whose action symbol nothing implements yet.

Distinct from NotFound, and the distinction is the point: NotFound means the operator typed a name that does not exist, while Unhandled means the editor ADVERTISED a binding — it is in --commands, it is in the keymap, --list-rc counts it — and then did nothing. The second is the more misleading of the two and used to be the silent one.

Failed(String)
