Trait Implementations

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.

fn deserial_ctx<R: Read>(
    size_len: 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.

impl<K: Serial, V: Serial> SerialCtx for HashMap<K, V>

Serialization for HashMap given a size_len. Keys are not serialized in any particular order.

fn serial_ctx<W: Write>(
    &self,
    size_len: SizeLength,
    out: &mut W
) -> Result<(), W::Err>

Attempt to write the structure into the provided writer, failing if if the length cannot be represented in the provided size_length or only part of the structure could be written.
