Function decode_u16 

pub fn decode_u16(buf: &mut ReadBuf<'_>) -> Result<u16>

Decode a u16 varint from buf.

Errors

• Error::UnexpectedEof if buf is exhausted before the terminator byte.
• Error::VarintOverflow if the decoded value exceeds u16::MAX or if more than MAX_LEN_U16 bytes would be consumed.

The cursor is unchanged on error.

Example

use wire_codec::{varint, ReadBuf};
let mut buf = ReadBuf::new(&[0xFF, 0xFF, 0x03]);
assert_eq!(varint::decode_u16(&mut buf).unwrap(), u16::MAX);
