pub type HashSet<K, S = FnvBuildHasher> = HashSet<K, S>;

Reexport of the HashSet from hashbrown with the default hasher set to the fnv hash function.

Aliased Type

struct HashSet<K, S = FnvBuildHasher> { /* private fields */ }

Trait Implementations

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

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.

fn deserial<R: Read>(source: &mut R) -> ParseResult<Self>

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

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.

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<T: SchemaType> SchemaType for HashSet<T>

fn get_type() -> Type

impl<K: Serial> Serial for HashSet<K>

sufficient for all realistic use cases in smart contracts. They are serialized in no particular order.

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

Attempt to write the structure into the provided writer, failing if only part of the structure could be written.

impl<K: Serial> SerialCtx for HashSet<K>

Serialization for HashSet given a size_len. Values 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.
