tracekv

The tracekv.Store implementation defines a store which wraps a parent KVStore and traces all operations performed on it. Each trace operation is written to a provided io.Writer object. Specifically, a TraceOperation object is JSON encoded and written to the writer. The TraceOperation object contains the exact operation, e.g. a read or write, and the corresponding key and value pair.

A tracekv.Store can also be instantiated with a store.TraceContext which can allow each traced operation to include additional metadata, e.g. a block height or hash.

Note, tracekv.Store is not meant to be branched or written to. The parent KVStore is responsible for all branching and writing operations, while a tracekv.Store wraps such a store and traces all relevant operations on it.
