Struct ParamAttrs

Source

pub(crate) struct ParamAttrs {
    pub coerce: bool,
    pub match_arg: bool,
    pub several_ok: bool,
    pub choices: Option<Vec<String>>,
    pub default: Option<String>,
}

Expand description

Collapsed per-parameter attribute state for a single function parameter.

Built during parsing from #[miniextendr(coerce | match_arg | several_ok | default = "…" | choices("…"))] on the argument. Accessors on MiniextendrFunctionParsed query this struct rather than looking through multiple side-tables.
