Struct flashmap::ReadGuard

source · [−]

pub struct ReadGuard<'guard, K, V, S = RandomState> { /* private fields */ }

Expand description

Provides immutable access to the map, and prevents entries from being dropped.

This guard provides a snapshot view of the map at a particular point in time. A new guard must be created in order to see updates from the writer. See ReadHandle::guard for examples. See View for additional examples and the public API to interact with the underlying map.
