ByteSize
ByteSize is an utility that easily makes bytes size representation and helps its arithmetic operations.
API Documentation
Usage
Add this to your Cargo.toml:
[dependencies]
bytesize = "0.2.0"
and this to your crate root:
extern crate bytesize;
Example
Arithmetic operations
extern crate bytesize;
use bytesize::ByteSize;
fn byte_arithmetic_operator() {
let x = ByteSize::mb(1);
let y = ByteSize::kb(100);
let plus = x + y;
print!("{}", plus);
let minus = ByteSize::tb(100) + ByteSize::gb(4);
print!("{}", minus);
}
