Struct 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.

Implementations

impl<C: 'static + Context> Args<C>

pub 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.

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

Converts a Value to an Args.

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

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

Trait Implementations

impl<C: 'static + Context> Clone for Args<C>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<C: 'static + Context> Debug for Args<C>

fn fmt(&self, fmt: &mut Formatter<'_>) -> FmtResult

Formats the value using the given formatter.

impl<C: 'static + Context> Display for Args<C>

fn fmt(&self, fmt: &mut Formatter<'_>) -> FmtResult

Formats the value using the given formatter.

impl<C: 'static + Context> Drop for Args<C>

fn drop(&mut self)

Executes the destructor for this type.

impl<C: 'static + Context> Finalize for Args<C>

fn finalize(&self)

impl<C: 'static + Context> PartialEq for Args<C>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<C: 'static + Context> Trace for Args<C>

unsafe fn trace(&self)

Marks all contained Gcs.

unsafe fn root(&self)

Increments the root-count of all contained Gcs.

unsafe fn unroot(&self)

Decrements the root-count of all contained Gcs.

fn finalize_glue(&self)

Runs Finalize::finalize() on this object and all contained subobjects
