Implementations

impl HashFunction

pub const fn collision_resistance(&self) -> u32

Returns the collision resistance level (in bits) of this hash function.

Trait Implementations

impl Clone for HashFunction

fn clone(&self) -> HashFunction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HashFunction

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Deserializable for HashFunction

fn read_from<R>(source: &mut R) -> Result<HashFunction, DeserializationError>

where R: ByteReader,

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn min_serialized_size() -> usize

Returns the minimum serialized size for one instance of this type.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_from_bytes_with_budget( bytes: &[u8], budget: usize, ) -> Result<Self, DeserializationError>

Deserializes Self from bytes with a byte budget limit.

impl<'de> Deserialize<'de> for HashFunction

fn deserialize<__D>( __deserializer: __D, ) -> Result<HashFunction, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for HashFunction

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HashFunction

fn eq(&self, other: &HashFunction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serializable for HashFunction

fn write_into<W>(&self, target: &mut W)

where W: ByteWriter,

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.

impl Serialize for HashFunction

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for HashFunction

type Error = InvalidHashFunctionError

fn try_from( hash_fn_str: &str, ) -> Result<HashFunction, <HashFunction as TryFrom<&str>>::Error>

Performs the conversion.

impl TryFrom<u8> for HashFunction

type Error = DeserializationError

The type returned in the event of a conversion error.

fn try_from( repr: u8, ) -> Result<HashFunction, <HashFunction as TryFrom<u8>>::Error>

Performs the conversion.
