Trait concordium_std::Deserial

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

The Deserial trait provides a means of reading structures from byte-sources (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.

Object Safety

This trait is not object safe.

Implementations on Foreign Types

impl Deserial for bool

Deserializing a bool reads one byte, and returns the value false if the byte is 0u8 and true if the byte is 1u8, every other value results in an error.

impl<K> Deserial for HashSet<K, BuildHasherDefault<FnvHasher>>

where K: Deserial + Hash + Eq,

The deserialization of sets assumes their size is a u32.

WARNING: Deserialization only ensures that there are no duplicates. Serializing a HashSet via its Serial instance will not lay out elements in any particular 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 use a BTreeSet instead.

impl<K> Deserial for BTreeSet<K>

where K: Deserial + Ord,

The deserialization of sets assumes their size is 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 a canonical order should be ensured to avoid subtle, difficult to diagnose, bugs.
