Struct MatchArgParamDocEntry

Source

pub struct MatchArgParamDocEntry {
    pub placeholder: &'static str,
    pub several_ok: bool,
    pub choices_str: fn() -> String,
}

Expand description

Entry for replacing match_arg @param doc placeholders with human-readable choice descriptions.

Fields§

§placeholder: &'static str

Placeholder string in the @param roxygen tag, e.g. ".__MX_MATCH_ARG_PARAM_DOC_match_arg_set_mode_mode__".

§several_ok: bool

true for several_ok params (emits “One or more of …”); false for plain match_arg (emits “One of …”).

§choices_str: fn() -> String

Function that returns the choices as a comma-separated quoted string, e.g. "\"Fast\", \"Safe\", \"Debug\"".
