Overview

Package size provides value size operations.

Index

• func Of(data interface{}) int
• func Stat(v interface{}, depth int, maxItem int) string

Examples

• Stat

Functions

func Of

func Of(data interface{}) int

Of returns the size in byte a value(not type) costs.

Since 0.1.0

func Stat

func Stat(v interface{}, depth int, maxItem int) string

Stat returns a multi line string describe size of every component of a vavlue, such as slice element, struct member:

   size_test.my: 48
	   a: []int32: 36
		   0: int32: 4
		   1: int32: 4
		   2: int32: 4
	   b: [3]int32: 12
		   0: int32: 4
		   1: int32: 4
		   2: int32: 4

Since 0.1.0

Example

package main

import (
	"fmt"
	"github.com/openacid/low/size"
)

func main() {
	type my struct {
		a []int32
		b [3]int32
	}

	v := my{
		a: []int32{1, 2, 3},
		b: [3]int32{4, 5, 6},
	}

	fmt.Println(size.Of(v))
	got := size.Stat(v, 10, 100)
	fmt.Println(got)

}

Output:

48
size_test.my: 48
    a: []int32: 36
        0: int32: 4
        1: int32: 4
        2: int32: 4
    b: [3]int32: 12
        0: int32: 4
        1: int32: 4
        2: int32: 4
