type Stack
Stack is a simple implementation of a stack data structure.
type Stack[T any] struct {
// contains filtered or unexported fields
}
func New
func New[T any]() Stack[T]
New returns a new stack.
Example
package main
import (
"atomicgo.dev/stack"
)
func main() {
stack.New[string]()
}
func (*Stack[T]) Clear
func (s *Stack[T]) Clear()
Clear removes all items from the stack.
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
s.Clear()
fmt.Println(s)
}
Output
[]
func (*Stack[T]) Contains
func (s *Stack[T]) Contains(item T) bool
Contains returns true if the stack contains the item.
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
fmt.Println(s.Contains("Hello"))
fmt.Println(s.Contains("Foo"))
}
Output
true
false
func (*Stack[T]) IsEmpty
func (s *Stack[T]) IsEmpty() bool
IsEmpty returns true if the stack is empty.
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
fmt.Println(s.IsEmpty())
s.Clear()
fmt.Println(s.IsEmpty())
}
Output
false
true
func (*Stack[T]) Peek
func (s *Stack[T]) Peek() T
Peek returns the top item of the stack without removing it.
func (*Stack[T]) Pop
func (s *Stack[T]) Pop() T
Pop removes an item from the stack and returns it. Panics if the stack is empty. Use PopSafe for safer access to the Stack.
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
fmt.Println(s.Pop())
fmt.Println(s.Pop())
}
Output
World
Hello
func (*Stack[T]) PopSafe
func (s *Stack[T]) PopSafe() T
PopSafe removes an item from the stack and returns it. Returns the zero value of the type if the stack is empty. To make this function safe, it uses reflection and is therefore slower than Pop.
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
fmt.Println(s.PopSafe())
fmt.Println(s.PopSafe())
fmt.Println(s.PopSafe())
}
Output
World
Hello
func (*Stack[T]) Push
func (s *Stack[T]) Push(item ...T)
Push adds items to a stack.
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
fmt.Println(s)
}
Output
[Hello World]
func (*Stack[T]) Size
func (s *Stack[T]) Size() int
Size returns the size of the stack.
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
fmt.Println(s.Size())
}
Output
2
func (Stack[T]) String
func (s Stack[T]) String() string
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
fmt.Println(s.String())
}
Output
[Hello World]
func (*Stack[T]) Values
func (s *Stack[T]) Values() []T
Values returns the values of the stack as a slice.
Example
package main
import (
"fmt"
"atomicgo.dev/stack"
)
func main() {
s := stack.New[string]()
s.Push("Hello")
s.Push("World")
fmt.Println(s.Values())
}
Output
[Hello World]

Types ¶
type Stack ¶
type Stack[T any] struct { // contains filtered or unexported fields }
Stack is a simple implementation of a stack data structure.
func (*Stack[T]) Peek ¶
func (s *Stack[T]) Peek() T
Peek returns the top item of the stack without removing it.
func (*Stack[T]) Pop ¶
func (s *Stack[T]) Pop() T
Pop removes an item from the stack and returns it. Panics if the stack is empty. Use PopSafe for safer access to the Stack.
func (*Stack[T]) PopSafe ¶
func (s *Stack[T]) PopSafe() T
PopSafe removes an item from the stack and returns it. Returns the zero value of the type if the stack is empty. To make this function safe, it uses reflection and is therefore slower than Pop.
