Overview ¶
Package stream implements a sequence of elements supporting sequential and operations. this package is an experiment to explore if stream in go can work as the way java does. its function is very limited.

Functions ¶
func Concat ¶
func Concat[T any](a, b stream[T]) stream[T]
Concat creates a lazily concatenated stream whose elements are all the elements of the first stream followed by all the elements of the second stream. Play: https://go.dev/play/p/HM4OlYk_OUC
Example ¶
s1 := FromSlice([]int{1, 2, 3})
s2 := FromSlice([]int{4, 5, 6})
s := Concat(s1, s2)
data := s.ToSlice()
fmt.Println(data)
Output: [1 2 3 4 5 6]
func FromChannel ¶
func FromChannel[T any](source <-chan T) stream[T]
FromChannel creates stream from channel. Play: https://go.dev/play/p/9TZYugGMhXZ
Example ¶
ch := make(chan int)
go func() {
for i := 1; i < 4; i++ {
ch <- i
}
close(ch)
}()
s := FromChannel(ch)
data := s.ToSlice()
fmt.Println(data)
Output: [1 2 3]
func FromRange ¶
func FromRange[T constraints.Integer | constraints.Float](start, end, step T) stream[T]
FromRange creates a number stream from start to end. both start and end are included. [start, end] Play: https://go.dev/play/p/9Ex1-zcg-B-
Example ¶
s := FromRange(1, 5, 1) data := s.ToSlice() fmt.Println(data)
Output: [1 2 3 4 5]
func FromSlice ¶
func FromSlice[T any](source []T) stream[T]
FromSlice creates stream from slice. Play: https://go.dev/play/p/wywTO0XZtI4
Example ¶
s := FromSlice([]int{1, 2, 3})
data := s.ToSlice()
fmt.Println(data)
Output: [1 2 3]
func Generate ¶
Generate stream where each element is generated by the provided generater function Play: https://go.dev/play/p/rkOWL1yA3j9
Example ¶
n := 0
max := 4
generator := func() func() (int, bool) {
return func() (int, bool) {
n++
return n, n < max
}
}
s := Generate(generator)
data := s.ToSlice()
fmt.Println(data)
Output: [1 2 3]
func Of ¶
func Of[T any](elems ...T) stream[T]
Of creates a stream whose elements are the specified values. Play: https://go.dev/play/p/jI6_iZZuVFE
Example ¶
s := Of(1, 2, 3) data := s.ToSlice() fmt.Println(data)
Output: [1 2 3]
