genericz

genericz - convenience made possible since generics

The main package contains

• Min(a ...T) T and Max(a ...T) T
• Ternary(cond bool, a, b T) T
• Coalesce(...T) T, CoalesceSlice(...T) T and CoalesceMap(...T) T
• SortWithData(comparables []C, data []D)

The packages below are intended to contain additions to golang.org/x/exp/slices and golang.org/x/exp/maps and thus won't be the full set that you need. (Over time there will be overlap as we won't remove methods as it would break backwards compatibility.)

mapz

The mapz package contains:

• KeysSorted(m map[K]V) []K, ValuesSorted(m map[K]V) []V and ValuesSortedByKey(m map[K]V) []V
• MinKey(m map[K]V) K and MaxKey(m map[K]V) K
• DeleteWithLock(l sync.Locker, m map[K]V, key K) and StoreWithLock(l sync.Locker, m map[K]V, key K, value V)
• Ordered(m map[K]V) iter.Seq2[K, V]

The SyncMap is a type-safe sync.Map.

The MutexMap is a variant of SyncMap that uses a mutex and a regular map.

The AppendMap is an append-only map perfect for caching values that never change. It slightly cheaper than a sync.Map because values can't change.

slicez

The slicez packages contains Diff, Filter, Map, Unique, Concat, Sum and Pop.

orderedobject

The orderedobject allows you to decode a JSON dict while preserving order. Can be used with most json encoders/decoders.
