Trait Implementations

impl CreateFilter for LevelDBFilterPolicy

fn create_filter(&self, keys: *const Slice, n: i32, dst: *mut String)

| keys[0,n-1] contains a list of keys | (potentially with duplicates) that are | ordered according to the user supplied | comparator. Append a filter that summarizes | keys[0,n-1] to *dst. | | Warning: do not change the initial contents | of *dst. Instead, append the newly | constructed filter to *dst.

impl Drop for LevelDBFilterPolicy

fn drop(&mut self)

Executes the destructor for this type.

impl KeyMayMatch for LevelDBFilterPolicy

fn key_may_match(&self, key_: &Slice, filter: &Slice) -> bool

| “filter” contains the data appended by | a preceding call to CreateFilter() on this | class. This method must return true if the | key was in the list of keys passed to | CreateFilter(). | | This method may return true or false if the | key was not on the list, but it should aim to | return false with a high probability.
