Does Go has out of the box priority queue? -


does go has out of box priority queue (the 1 can import module , start using python's priority queue)?

i know priority queues implemented using heap data structure , go has heap package, suggests how use implement queue (in example (priorityqueue) ), can grab , use.

my question recommended way this, or there out of box priority queue package failed find?

quoting wikipedia:

a priority queue abstract data type regular queue or stack data structure, additionally each element has "priority" associated it. [...] while priority queues implemented heaps, conceptually distinct heaps. priority queue abstract concept "a list" or "a map";

go provides basic data structures used in applications leave implementation of more specialized data structures programmer. example, go map can used trivially implement set.

the example link uses slice []*item represent more abstract type heap.interface , (even more abstract) type priorityqueue. go composition , implementing priorityqueue in terms of heap operations practice.

this gives control programmer. if want thread safety, use composition of priorityqueue , sync.mutex make thread safe. if want different implementation heap, make priorityqueue interface , can implement want.

of course there's trade-off. in case, implementation ~25 lines of code. if implementation hundreds of lines you'd want find package has done already.
