memdb

type MemDB ¶

type MemDB struct {
	// contains filtered or unexported fields
}

MemDB is an in-memory database backend using a B-tree for storage.

For performance reasons, all given and returned keys and values are pointers to the in-memory database, so modifying them will cause the stored values to be modified as well. All DB methods already specify that keys and values should be considered read-only, but this is especially important with MemDB.
