Structs
| BloomPolicy |
A filter policy using a bloom filter internally. |
| InternalFilterPolicy |
A filter policy wrapping another policy; extracting the user key from internal keys for all operations. A User Key is u8*. An Internal Key is u8* u8{8} (where the second part encodes a tag and a sequence number). |
| NoFilterPolicy |
Used for tables that don't have filter blocks but need a type parameter. |
Traits
| FilterPolicy |
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
| BoxedFilterPolicy |
A boxed and refcounted filter policy (reference-counted because a Box with unsized content couldn't be cloned otherwise) |
