Trait Implementations

source

impl<F> CompactionFilter for CompactionFilterCallback<F> where
F: CompactionFilterFn,

source

fn name(&self) -> &CStr

Returns a name that identifies this compaction filter. The name will be printed to LOG file on start up for diagnosis. Read more

source

fn filter(&mut self, level: u32, key: &[u8 ], value: &[u8 ]) -> Decision

The compaction process invokes this method for kv that is being compacted. The application can inspect the existing value of the key and make decision based on it. Read more
