[dependabot]

Bumps github.com/puzpuzpuz/xsync/v3 from 3.2.0 to 3.4.0.

Release notes

Sourced from github.com/puzpuzpuz/xsync/v3's releases.

v3.4.0

• Add optimistic locking methods to RBMutex #138 and #140
• Fix Map/MapOf capacity calculation for WithPresize #139

RBMutex now has methods for optimistic locking:

mu := xsync.NewRBMutex()
if locked, t := mu.TryRLock(); locked {
	// critical reader section...
	mu.RUnlock(t)
}
if mu.TryLock() {
	// critical writer section...
	mu.Unlock()
}

Thanks @​kkroo for the contribution.

v3.3.1

• Add NewMapOfWithHasher function #137

Adds NewMapOfWithHasher function to support custom hash functions in MapOf:

m := NewMapOfWithHasher[int, int](https://github.com/puzpuzpuz/xsync/blob/HEAD/func(i int, _ uint64) uint64 {
	// Murmur3 finalizer. No DDOS protection as it does not support seed.
	h := uint64(i)
	h = (h ^ (h >> 33)) * 0xff51afd7ed558ccd
	h = (h ^ (h >> 33)) * 0xc4ceb9fe1a85ec53
	return h ^ (h >> 33)
})

Some custom hash functions may be faster than the built-in function if the lack of DDOS protection is fine.
