Struct ExVerb 

pub struct ExVerb {
    pub full: &'static str,
    pub min: usize,
    pub plain: &'static str,
    pub forced: &'static str,
}

One ex command’s spelling rule.

plain and forced are separate registered command names rather than one name plus a bang argument. A command body receives &[String] and nothing else, so a bang passed as an argument is a convention every body has to remember to read — and the one that forgets quits without asking. Two names cannot be misread, and both show up in --commands saying what they do. Verbs for which ! changes nothing (writing has no force semantics here — escriba has no read-only flag to override) point both fields at the same command, which is the honest encoding of “the bang is accepted and means nothing”.

Fields

full: &'static str

The full spelling, as :help ex-cmd-index writes it.

min: usize

The fewest characters that select it. full[..min] is what vim prints in square-bracket notation: :q[uit] is ("quit", 1).

plain: &'static str

The registered command the plain form dispatches to.

forced: &'static str

The registered command the ! form dispatches to.
