Struct canadensis::core::session::SessionDynamicMap
source · [−]pub struct SessionDynamicMap<I, N, T, D> where
I: Instant, { /* private fields */ }Expand description
A session map that uses dynamic memory allocation
Caution: This implementation cannot detect when memory allocation fails, so it may cause the program to abort. Only use it when memory is plentiful.
This implementation uses variable amounts of memory and takes O(log(number of sessions)) time.
