type Stack ¶
type Stack[T any] interface { // Len returns size of Stack Len() int // Push pushes element to head of Stack Push(v T) // Pop pops element from head of Stack Pop() (T, bool) // Top returns top element of Stack Top() (T, bool) // Clear releases all the entries, resulting in an empty Stack. Clear() // Range calls f sequentially for each element present in the Stack. // If f returns false, range stops the iteration. Range(func(T) bool) }
Example ¶
package main
import (
"fmt"
"github.com/xoctopus/x/container/stack"
)
func main() {
for _, s := range []stack.Stack[any]{
stack.NewSafeStack[any](),
stack.NewStack[any](),
} {
s.Push(1)
s.Push(2)
s.Push(3)
s.Push(4)
top, _ := s.Top()
fmt.Println("top:", top)
v, _ := s.Pop()
fmt.Println(v)
for v = range s.Range {
fmt.Println(v)
}
s.Clear()
fmt.Println("len:", s.Len())
_, ok := s.Top()
fmt.Println("top:", ok)
_, ok = s.Pop()
fmt.Println("pop:", ok)
}
}
Output: top: 4 4 3 2 1 len: 0 top: false pop: false top: 4 4 3 2 1 len: 0 top: false pop: false
