Structs
- A filter policy using a bloom filter internally.
- Used for tables that don’t have filter blocks but need a type parameter.
Traits
- Encapsulates a filter algorithm allowing to search for keys more efficiently. Usually, policies are used as a BoxedFilterPolicy (see below), so they can be easily cloned and nested.
Type Definitions
- A boxed and refcounted filter policy (reference-counted because a Box with unsized content couldn’t be cloned otherwise)
