Trait concordium_std::Deserial

pub trait Deserial {
    fn deserial<R>(_source: &mut R) -> Result<Self, ParseError>
    where
        R: Read;
}

The Deserial trait provides a means of reading structures from byte-sinks (Read).

Can be derived using #[derive(Deserial)] for most cases.

Required methods

fn deserial<R>(_source: &mut R) -> Result<Self, ParseError> where
    R: Read, 

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

The deserialization of sets assumes their size as a u32.

WARNING: Deserialization does not ensure the ordering of the keys, it only ensures that there are no duplicates. Serializing a BTreeSet via its Serial instance will lay out elements by the increasing order. As a consequence deserializing, and serializing back is in general not the identity. This could have consequences if the data is hashed, or the byte representation is used in some other way directly. In those cases the a canonical order should be ensured to avoid subtle, difficult to diagnose, bugs.
