Function concordium_std::deserial_map_no_length

pub fn deserial_map_no_length<R, K, V>(
    source: &mut R,
    len: usize
) -> Result<BTreeMap<K, V, Global>, ParseError>where
    R: Read,
    K: Deserial + Ord + Copy,
    V: Deserial,

Read a BTreeMap as a list of key-value pairs given some length. NB: This ensures there are no duplicates, hence the specialized type. Moreover this will only succeed if keys are listed in order.
