StructBuf
This library provides a capacity-limited buffer for encoding and decoding structured data. The primary use case is for safely handling small, variable-length message packets sent over the network or other transports.
The encoder ensures that the message size never exceeds a pre-configured limit. The decoder ensures that malformed or malicious input does not cause the program to panic.
no_std
support
structbuf
is no_std
by default.
Example
cargo add structbuf
use structbuf::StructBuf;
let mut b = StructBuf::new(4);
b.append().u8(1).u16(2_u16).u8(3);
// b.u8(4); Would panic
let mut p = b.unpack();
assert_eq!(p.u8(), 1);
assert_eq!(p.u16(), 2);
assert_eq!(p.u8(), 3);
assert!(p.is_ok());
assert_eq!(p.u32(), 0);
assert!(!p.is_ok());
