Trait Implementations

impl AsRef<[u8]> for Hash

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Hash

fn clone(&self) -> Hash

Returns a copy of the value.

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

Formats the value using the given formatter.

impl Decode for Hash

fn try_default() -> Result<Self, DecodeError>

Try to decode from a missing/null/undefined value.

fn try_from_cbor_value(value: Value) -> Result<Self, DecodeError>

Try to decode from a given CBOR value.

fn try_from_cbor_value_default(value: Value) -> Result<Self, DecodeError>

where Self: Sized,

Try to decode from a given CBOR value, calling try_default in case the value is null or undefined.

impl Default for Hash

fn default() -> Self

Returns the “default value” for a type.

impl Display for Hash

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

Formats the value using the given formatter.

impl Encode for Hash

fn into_cbor_value(self) -> Value

Encode the type into a CBOR Value.

fn is_empty(&self) -> bool

Whether the value is equal to the empty value for the type.

impl From<&[u8]> for Hash

fn from(b: &[u8]) -> Hash

Converts to this type from the input type.

impl From<&'static str> for Hash

fn from(s: &'static str) -> Hash

Converts to this type from the input type.

impl From<Hash> for [u8; 32]

fn from(b: Hash) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Hash

fn from(v: Vec<u8>) -> Hash

Converts to this type from the input type.

impl FromStr for Hash

type Err = FromHexError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Hash, FromHexError>

Parses a string s to return a value of this type.

impl Hash for Hash

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 KeyFormatAtom for Hash

fn size() -> usize

fn encode_atom(self) -> Vec<u8>

fn decode_atom(data: &[u8]) -> Self

where Self: Sized,

impl LowerHex for Hash

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

Formats the value using the given formatter.

impl Ord for Hash

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Hash

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Hash

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Zeroize for Hash

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl Copy for Hash

impl Eq for Hash
