sync package - sync - Go Packages

Package sync provides basic synchronization primitives such as mutual exclusion locks. Other than the Once and WaitGroup types, most are intended for use by low-level library routines. Higher-level synchronization is better done via channels and communication. Values containing the types defined in this package should not be copied. This section is empty. This section is empty. OnceFunc returns a function that invokes f only once. The returned function may be called concurrently. If f panics, the returned function will panic with the same value on every call. OnceValue returns a function that invokes f only once and returns the value returned by f. The returned function may be called concurrently. If f panics, the returned function will panic with the same value on every call. OnceValues returns a function that invokes f only once and returns the values returned by f. The returned function may be called concurrently. If f panics, the returned function will panic with the same value on
