Types

type KeyMutex

type KeyMutex interface {
	// Acquires a lock associated with the specified ID, creates the lock if one doesn't already exist.
	LockKey(id string)

	// Releases the lock associated with the specified ID.
	// Returns an error if the specified ID doesn't exist.
	UnlockKey(id string) error
}

KeyMutex is a thread-safe interface for acquiring locks on arbitrary strings.

func NewHashed added in v1.12.0

func NewHashed(n int) KeyMutex

NewHashed returns a new instance of KeyMutex which hashes arbitrary keys to a fixed set of locks. `n` specifies number of locks, if n <= 0, we use number of cpus. Note that because it uses fixed set of locks, different keys may share same lock, so it's possible to wait on same lock.
