DropLast drops n elements from the end of a sequence.

go
collection := func(yield func(int) bool) {
    yield(1)
    yield(2)
    yield(3)
    yield(4)
    yield(5)
}

filtered := it.DropLast(collection, 2)
var result []int
for item := range filtered {
    result = append(result, item)
}
// result contains [1, 2, 3]

DropByIndex drops elements from a sequence by the index.

go
collection := func(yield func(int) bool) {
    yield(1)
    yield(2)
    yield(3)
    yield(4)
    yield(5)
}

filtered := it.DropByIndex(collection, 1, 3)
var result []int
for item := range filtered {
    result = append(result, item)
}
// result contains [1, 3, 5]

Subset returns a subset of a sequence from offset up to length elements.

go
collection := func(yield func(int) bool) {
    yield(1)
    yield(2)
    yield(3)
    yield(4)
    yield(5)
    yield(6)
}

subset := it.Subset(collection, 2, 3)
var result []int
for item := range subset {
    result = append(result, item)
}
// result contains [3, 4, 5]

Slice returns a subset of a sequence from start up to, but not including end.

go
collection := func(yield func(int) bool) {
    yield(1)
    yield(2)
    yield(3)
    yield(4)
    yield(5)
}

sliced := it.Slice(collection, 1, 4)
var result []int
for item := range sliced {
    result = append(result, item)
}
// result contains [2, 3, 4]
