Structs§

Constants§

ACTIVE_RESOLUTIONS 🔒
During import resolution, recursive imports can form cycles. This set stores the active resolution stack for the current thread. So it’s essentially a recursion stack.

Functions§

enter_cycle_detector 🔒
Returns Err(()) if a cycle is detected, otherwise this returns a guard that will remove the resolution when dropped.
