Struct ByteRange 

pub struct ByteRange { /* private fields */ }

获取字节范围描述

• start 开始位置
• amount 获取字节数量，支持负数

example

use xt_oss::util::ByteRange;
assert_eq!(ByteRange::new().to_string(), "bytes=0-");
assert_eq!(ByteRange::new().with_amount(500).to_string(), "bytes=0-499");
assert_eq!(ByteRange::new().with_amount(-500).to_string(), "bytes=-500");
assert_eq!(ByteRange::new().with_start(100).to_string(), "bytes=100-");
assert_eq!(ByteRange::from((100, 500)).to_string(), "bytes=100-599");
assert_eq!(ByteRange::from((100, -500)).to_string(), "bytes=0-99");
assert_eq!(ByteRange::from((100, -50)).to_string(), "bytes=50-99");
