pub struct NativeFunction { /* private fields */ }

Implementations

impl NativeFunction

pub fn new(
    signature: Signature,
    defaults: Option<Box<[Variant]>>,
    env: Gc<GlobalEnv>,
    func: NativeFn
) -> Self

pub fn signature(&self) -> &Signature

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

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 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.
