Implementations

impl NativeFunction

pub fn signature(&self) -> &Signature

pub fn env(&self) -> Gc<NamespaceEnv>

pub fn defaults(&self) -> &[Variant]

pub fn exec_fun( &self, vm: &mut VirtualMachine<'_>, args: &[Variant], ) -> ExecResult<Variant>

actually execute a native function

Trait Implementations

impl Debug for NativeFunction

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

Formats the value using the given formatter.

impl From<NativeFunction> for Variant

fn from(func: NativeFunction) -> Self

Converts to this type from the input type.

impl GcTrace for NativeFunction

fn trace(&self)

SAFETY: Must call Gc::mark_trace() on every reachable Gc handle

fn size_hint(&self) -> usize

If the GcTrace owns any allocations, this should return the extra allocated size. If the allocation can change size, like a Vec, then don’t include it in the size hint, or return a const estimate of the average size.

fn cleanup(&self)
