# size - calculates variable's memory consumption at runtime
### Part of the [Transflow Project](http://transflow.ru/)
Sometimes you may need a tool to measure the size of object in your Go program at runtime. This package makes an attempt to do so. Package based on `binary.Size()` from Go standard library.
Features:
- supports non-fixed size variables and struct fields: `struct`, `int`, `slice`, `string`, `map`;
- supports complex types including structs with non-fixed size fields;
- supports all basic types (numbers, bool);
- supports `chan` and `interface`;
- supports pointers;
- implements infinite recursion detection (i.e. pointer inside struct field references to parent struct).
### Usage example
```
package main
import (
"fmt"
// Use latest tag.
"github.com/DmitriyVTitov/size"
)
func main() {
a := struct {
a int
b string
c bool
d int32
e []byte
f [3]int64
}{
a: 10, // 8 bytes
b: "Text", // 16 (string itself) + 4 = 20 bytes
c: true, // 1 byte
d: 25, // 4 bytes
e: []byte{'c', 'd', 'e'}, // 24 (slice itself) + 3 = 27 bytes
f: [3]int64{1, 2, 3}, // 3 * 8 = 24 bytes
} // 84 + 3 (padding) = 87 bytes
fmt.Println(size.Of(a))
}
// Output: 87
```
