Overview ¶

Package db implements a simple key-value database. The database is cached in memory and mirrored on disk. It is used to store corpus in syz-manager and syz-hub. The database strives to minimize number of disk accesses as they can be slow in virtualized environments (GCE).

Types ¶

type DB ¶

type DB struct {
	Version uint64            // arbitrary user version (0 for new database)
