Trait concordium_std::DeserialCtx

pub trait DeserialCtx: Sized {
    fn deserial_ctx<R: Read>(
        size_length: SizeLength, 
        ensure_ordered: bool, 
        source: &mut R
    ) -> ParseResult<Self>;
}

The DeserialCtx trait provides a means of reading structures from byte-sources (Read) using contextual information. The contextual information is:

• size_length: The expected number of bytes used for the length of the data.
• ensure_ordered: Whether the ordering should be ensured, for example that keys in BTreeMap and BTreeSet are in strictly increasing order.

Required methods

fn deserial_ctx<R: Read>(
    size_length: SizeLength,
    ensure_ordered: bool,
    source: &mut R
) -> ParseResult<Self>

Attempt to read a structure from a given source and context, failing if an error occurs during deserialization or reading.

Implementors

impl DeserialCtx for String

impl<K: Deserial + Eq + Hash> DeserialCtx for HashSet<K>

Deserialization for HashSet given a size_len. Values are not verified to be in any particular order and setting ensure_ordering have no effect.

impl<K: Deserial + Eq + Hash, V: Deserial> DeserialCtx for HashMap<K, V>

Deserialization for HashMap given a size_len. Keys are not verified to be in any particular order and setting ensure_ordering have no effect.

impl<K: Deserial + Ord + Copy> DeserialCtx for BTreeSet<K>

impl<K: Deserial + Ord + Copy, V: Deserial> DeserialCtx for BTreeMap<K, V>

impl<T: Deserial> DeserialCtx for Vec<T>
