Function deserialize_exact 

pub fn deserialize_exact<'de, T>(src: &'de [u8]) -> ReadResult<T>
where
    T: SchemaRead<'de, DefaultConfig, Dst = T>,

Deserialize a type from the given bytes and reject trailing bytes.

Examples

let bytes = wincode::serialize(&123u64).unwrap();
let value: u64 = wincode::deserialize_exact(&bytes).unwrap();
assert_eq!(value, 123);

let mut extra = bytes.clone();
extra.push(0xAA);
assert!(wincode::deserialize_exact::<u64>(&extra).is_err());
