}

Helper trait for inserting serialized typed (Key, Value) pairs into rocksdb.

Deprecation

This trait should not be used in new code, use [WriteTypedBatch] instead.

Required Methods

fn zs_insert<C, K, V>(&mut self, cf: &C, key: K, value: V)

where C: AsColumnFamilyRef, K: IntoDisk + Debug, V: IntoDisk,

Serialize and insert the given key and value into a rocksdb column family, overwriting any existing value for key.

fn zs_merge<C, K, V>(&mut self, cf: &C, key: K, value: V)

where C: AsColumnFamilyRef, K: IntoDisk + Debug, V: IntoDisk,

Serialize and merge the given key and value into a rocksdb column family, merging with any existing value for key.

fn zs_delete<C, K>(&mut self, cf: &C, key: K)

where C: AsColumnFamilyRef, K: IntoDisk + Debug,

Remove the given key from a rocksdb column family, if it exists.

fn zs_delete_range<C, K>(&mut self, cf: &C, from: K, until_strictly_before: K)

where C: AsColumnFamilyRef, K: IntoDisk + Debug,

Delete the given key range from a rocksdb column family, if it exists, including from and excluding until_strictly_before.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
