Struct CallFrame

pub(crate) struct CallFrame<'brw, 'rt> {
    env: &'brw mut Rt<Env<'rt>>,
}

A function call Frame.

This is a guard type that will pop the frame when it goes out of scope.

Fields

env: &'brw mut Rt<Env<'rt>>

Implementations

impl<'brw, 'rt> CallFrame<'brw, 'rt>

pub(crate) fn new(env: &'brw mut Rt<Env<'rt>>) -> Self

Create a new function call frame with a drop guard to be removed when this goes out of scope.

pub(crate) fn new_with_args(env: &'brw mut Rt<Env<'rt>>, args: usize) -> Self

Create a new function call frame with the top args on the stack. This frame will be removed when the CallFrame goes out of scope.

pub(crate) fn push_arg(&mut self, arg: impl IntoRoot<Slot<Gc<ObjectType<'rt>>>>)

Push an argument onto the stack as part of this call frame

pub(crate) fn finalize_arguments(&mut self)

Set the total argument count before a function call

pub(crate) fn arg_count(&self) -> usize

pub(crate) fn arg_slice(&self) -> &[Rt<Slot<Gc<ObjectType<'rt>>>>]

pub(crate) fn push_arg_slice(&mut self, src: &[Gc<ObjectType<'_>>])

Push a slice of arguments onto the stack as part of this call frame.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for CallFrame<'_, '_>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Drop for CallFrame<'_, '_>

fn drop(&mut self)

Executes the destructor for this type.
