Required Methods§

Source

fn merge_cf_full<K, V>( &self, cf: Option<&ColumnFamily>, key: K, value: V, writeopts: Option<&W>, ) -> Result<(), Error>
where K: AsRef<[u8]>, V: AsRef<[u8]>,

Provided Methods§

Source

fn merge_cf<K, V>( &self, cf: &ColumnFamily, key: K, value: V, ) -> Result<(), Error>
where K: AsRef<[u8]>, V: AsRef<[u8]>,

Source

fn merge_cf_opt<K, V>( &self, cf: &ColumnFamily, key: K, value: V, writeopts: &W, ) -> Result<(), Error>
where K: AsRef<[u8]>, V: AsRef<[u8]>,

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
