Trait rustpython_vm::object::MaybeTraverse

pub trait MaybeTraverse {
    const IS_TRACE: bool = false;

    // Required method
    fn try_traverse(&self, traverse_fn: &mut TraverseFn<'_>);
}

This trait is used as a “Optional Trait”(I ’d like to use Trace? but it’s not allowed yet) for PyObjectPayload type

impl for PyObjectPayload, pyclass proc macro will handle the actual dispatch if type impl Trace Every PyObjectPayload impl MaybeTrace, which may or may not be traceable

Provided Associated Constants

const IS_TRACE: bool = false

if is traceable, will be used by vtable to determine

Required Methods

fn try_traverse(&self, traverse_fn: &mut TraverseFn<'_>)
