buf-view
A utility library to read and write primitive types on a wrapped buffer.
usage
To use buf-view
, first add this to your Cargo.toml
:
[dependencies]
buf-view = "0.1.0"
BufView
Wrap a buffer to read only.
use buf_view::BufView;
let buf = [0, 1, 2, 3, 4, 5, 6, 7];
let mut buf_view = BufView::wrap(&buf);
assert_eq!(buf_view.read_u8(), 0);
assert_eq!(buf_view.read_u16(), 0x0102);
assert_eq!(buf_view.read_u32(), 0x03040506);
assert_eq!(buf_view.get_u16(1), 0x0102);
// wrap from vector
let v = vec![0, 1, 2, 3, 4, 5, 6, 7];
let mut buf_view = BufView::wrap(v.as_slice());
assert_eq!(buf_view.read_u8(), 0);
assert_eq!(buf_view.read_u32(), 0x01020304);
// wrap from &str
let s = "01234567";
let mut buf_view = BufView::wrap(s.as_bytes());
assert_eq!(buf_view.read_u8(), 0x30);
assert_eq!(buf_view.read_u32(), 0x31323334);
BufViewMut
Wrap a buffer to read and write.
use buf_view::BufViewMut;
let mut buf = [0u8;7];
let mut buf_view = BufViewMut::wrap(&mut buf);
buf_view.write_u8(0);
buf_view.write_u16(0x0102);
buf_view.write_u32(0x03040506);
assert_eq!(buf_view.read_u8(), 0);
assert_eq!(buf_view.read_u16(), 0x0102);
assert_eq!(buf_view.read_u32(), 0x03040506);
assert_eq!(buf_view.get_u16(1), 0x0102);
