Struct canadensis_core::session::SessionDynamicMap

pub struct SessionDynamicMap<I, N, T, D>where
    I: Instant,{ /* private fields */ }

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.

Trait Implementations

impl<I, N, T, D> Default for SessionDynamicMap<I, N, T, D>where I: Instant, N: Ord,
