Enum umbra_lang::FnArgs

pub enum FnArgs {
    Macro {
        vars: HashableMap<String, RefTVal>,
        pos: Option<Pos>,
        tokens: Vec<Token>,

    Normal {
        this: Box<RefTVal>,

        args: RefTVal,
    },
}

Function arguments for various types of functions.

Variants

Macro

A way to call a function with Tokens as arguments rather than their evaluated forms.

Fields of Macro

vars: HashableMap<String, RefTVal>

The variables that the macro has access to.

pos: Option<Pos>

The position of the macro call.

tokens: Vec<Token>

The Tokens captured by the macro.

Normal

The usual way to call a function.

Note that this doesn’t have vars since function values are evaluated beforehand.

Fields of Normal

this: Box<RefTVal>

A reference to the called function.

pos: Option<Pos>

The position of the function call.

args: RefTVal

A reference to the function argument list.
