Enum ffi_support::handle_map::HandleError [−][src]
pub enum HandleError { NullHandle, InvalidHandle, StaleVersion, IndexPastEnd, WrongMap, }
Expand description
An error representing the ways a Handle
may be invalid.
Variants
Identical to invalid handle, but has a slightly more helpful message for the most common case 0.
Returned from Handle::from_u64
if Handle::is_valid
fails.
Returned from get/get_mut/delete if the handle is stale (this indicates something equivalent to a use-after-free / double-free, etc).
Returned if the handle index references an index past the end of the HandleMap.
The handle has a map_id for a different map than the one it was attempted to be used with.
