Struct Param 

pub struct Param {
    pub name: String,
    pub domain: Option<String>,
    pub default: Option<ParamDefault>,
    pub optional: bool,
    pub keyword_only: bool,
    pub positional_only: bool,
    pub alternate_names: Vec<String>,
    pub variable: bool,
}

One ordered parameter of a function entry.

Fields

name: String

domain: Option<String>

The enum domain this parameter requires, when it is an enum argument.

default: Option<ParamDefault>

An explicit default the frontend may expand; see ParamDefault.

optional: bool

Whether the argument is omittable without an emitted expansion ("optional": true; the reference accepts the short form).

keyword_only: bool

Whether the argument must be passed as a keyword (name = expr): the reference chase form requires its 3rd argument to be rate = ... or duration = ... (issue #110).

positional_only: bool

Whether the argument can only be passed positionally (keyword binding is rejected): the reference chase form’s leading arguments (issue #110).

alternate_names: Vec<String>

Additional accepted keyword spellings for this parameter (the reference chase form accepts both rate and duration for its 3rd argument).

variable: bool

Whether the argument must be a variable reference (a global variable or a player variable); the chase family requires a variable first argument to select the global/player emission form.
