Enum SurfaceForm 

pub enum SurfaceForm {
    Keyword,
    Delimiter {
        hint: Cow<'static, str>,
    },
}

How the user types this command on the : line. The default (Keyword) covers most commands – :write, :quit, :set number. Delimiter is for the small family of commands whose arguments are interleaved with delimiters: :s/pat/repl/, :g/pat/body, :v/pat/body. The keyword form (:ex:substitute, :ex:global) for these is intentionally a hard error – the front-end parser routes them via try_parse_substitute / try_parse_global. UI surfaces (completion, command palette) hide Delimiter commands because there’s no useful keyword-form completion for them; the user types the delimiter directly.

Variants

Keyword

Type the command word, optionally with !, then args separated by whitespace. The default for most commands.

Delimiter

Type a delimiter prefix followed by a body. The keyword form errors with a redirect message; the embedded hint is the canonical syntax shown in that error (:s/pat/repl/, :g/pat/body).

Fields

hint: Cow<'static, str>

The canonical syntax shown in the redirect error and in help, e.g. :s/pat/repl/.
