Arena memory allocator for Go
Experimental pooled memory allocator for Go.
It can be used like this:
package main
import (
"github.com/mibes/go-arena/pkg/arena"
)
type Tree struct {
Left *Tree
Right *Tree
}
func main() {
a := arena.NewArena(Tree{})
tree := (*Tree)(a.Alloc())
left := (*Tree)(a.Alloc())
right := (*Tree)(a.Alloc())
tree.Right, tree.Left = right, left
a.Release()
}
Alternative example:
package main
import (
"fmt"
"github.com/mibes/go-arena/pkg/arena"
)
type User struct {
firstName string
lastName string
age int
}
func main() {
a := arena.NewArena(User{})
user := (*User)(a.Alloc())
user.firstName = "Marcel"
fmt.Printf("%s %s: %d\n", user.firstName, user.lastName, user.age)
a.Release()
}
