stack
Lightweight, Simple, Quick, Thread-Safe Golang Stack Implementation
Purpose
Provide a fast, thread safe, and generic Golang Stack API with minimal external linkage and maximum performance and usability.
Installation
go get -d -v github.com/lossdev/stack
Example
package main
import (
"github.com/lossdev/stack"
"log"
"fmt"
)
type foo struct {
bar string
baz bool
}
func main() {
// declare a new Stack 's' with int type (stack.Int)
s := stack.NewStack(stack.Int)
if err := s.Push(1); err != nil {
log.Println(err)
}
if recv, err := stack.ToInt(s.Peek()); err != nil {
log.Println(err)
} else {
fmt.Println(recv)
}
// Adding a member of a different type than what s is declared as will error
if err := s.Push("Hello, World!"); err != nil {
log.Println(err)
}
gs := stack.NewGenericStack()
f := foo{"Hello, World!", true}
gs.Push(f)
if recv, err := gs.Peek(); err != nil {
log.Println(err)
} else {
// type assertion needed
frecv := recv.(foo)
fmt.Printf("GenericStack: {%s, %t}\n", frecv.bar, frecv.baz)
}
}
