Struct oftlisp::ast::Args

pub struct Args<C: 'static + Context> {
    pub required: Vec<Symbol>,
    pub optional: Vec<(Symbol, Gc<Value<C>>)>,
    pub rest: Option<Symbol>,
}

A type that represents the arguments specified for a function.

Fields

required: Vec<Symbol>

The required arguments.

optional: Vec<(Symbol, Gc<Value<C>>)>

The optional arguments, and their default values.

rest: Option<Symbol>

The rest argument, if any.

Methods

impl<C: 'static + Context> Args<C>

fn bind(
    &self,
    name: Option<Symbol>,
    args: Vec<Gc<Value<C>>>
) -> Result<GcLinkedList<(Symbol, Gc<Value<C>>)>, ArgsBindingError<C>>

Attempts to bind a list of arguments to the names specified in the Args object.

fn from_value(value: Gc<Value<C>>) -> Result<Args<C>, ArgsConvertError<C>>

Converts a Value to an Args.

fn to_value(&self) -> Gc<Value<C>>

Converts the Args back to a Value. In general, don't do this.
