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:

toml [dependencies] buf-view = "0.1.0"

BufView

Wrap a buffer to read only.

```rust use buf_view::BufView;

let buf = [0, 1, 2, 3, 4, 5, 6, 7]; let mut buf_view = BufView::wrap(&buf);

asserteq!(bufview.readu8(), 0); asserteq!(bufview.readu16(), 0x0102); asserteq!(bufview.readu32(), 0x03040506); asserteq!(bufview.getu16(1), 0x0102);

// wrap from vector let v = vec![0, 1, 2, 3, 4, 5, 6, 7]; let mut bufview = BufView::wrap(v.asslice()); asserteq!(bufview.readu8(), 0); asserteq!(bufview.readu32(), 0x01020304);

// wrap from &str let s = "01234567"; let mut bufview = BufView::wrap(s.asbytes()); asserteq!(bufview.readu8(), 0x30); asserteq!(bufview.readu32(), 0x31323334); ```

BufViewMut

Wrap a buffer to read and write.

```rust use buf_view::BufViewMut;

let mut buf = [0u8;7]; let mut buf_view = BufViewMut::wrap(&mut buf);

bufview.writeu8(0); bufview.writeu16(0x0102); bufview.writeu32(0x03040506);

asserteq!(bufview.readu8(), 0); asserteq!(bufview.readu16(), 0x0102); asserteq!(bufview.readu32(), 0x03040506); asserteq!(bufview.getu16(1), 0x0102); ```
