go

Go Source code for UnMango

A collection of random Go packages.

iter

Builds on the standard iter package. Re-exports Seq and Seq2 and adds Seq3. Adds a few sequence creation functions such as Empty and Singleton.

var seq Seq[int] = iter.Empty[int]()
var seq Seq[int] = iter.Singleton[int]()

maps

Currently only adds Collect for creating a map[] from a Seq2.

func Test(seq iter.Seq2[string, int]) {
	var m map[string]int = maps.Collect(seq)
}

result

Adds the Result type representing either success or error. Adds various result operations such as Map and Bind.

func main() {
	var r Result[int] = func() (int, error) {
		return 420, nil
	}

	r = result.Map(r, func(x int) int {
		return x+1
	})
}

seqs

Adds various sequence operations such as Map.

func Test(seq iter.Seq[int]) {
	seqs.Map(seq, func(x int) int {
		return x+1
	})
}

slices

Currently only re-exports Collect.

Inspiration

I stand on the shoulders of giants. A lot of this is inspired by the works of others, be sure to check out these repos as well. (They're much smarter than me)

Addendum

Idk if this repo structure is a good idea, but the short import is nice.

It wasn't, at least right away.
