Trait Implementations

impl Clone for Fingerprint

fn clone(&self) -> Fingerprint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Fingerprint

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

Formats the value using the given formatter.

impl<D: Decoder> Decodable<D> for Fingerprint

fn decode(d: &mut D) -> Self

impl Display for Fingerprint

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

Formats the value using the given formatter.

impl<E: Encoder> Encodable<E> for Fingerprint

fn encode(&self, s: &mut E)

impl From<Fingerprint> for PackedFingerprint

fn from(f: Fingerprint) -> PackedFingerprint

Converts to this type from the input type.

impl From<PackedFingerprint> for Fingerprint

fn from(f: PackedFingerprint) -> Fingerprint

Converts to this type from the input type.

impl FromStableHash for Fingerprint

type Hash = SipHasher128Hash

fn from(StableHasherHash: Self::Hash) -> Self

Convert the finalized state of a StableHasher and construct an Self containing the processed hash.

impl Hash for Fingerprint

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

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<CTX> HashStable<CTX> for Fingerprint

fn hash_stable(&self, _: &mut CTX, hasher: &mut StableHasher)

impl Ord for Fingerprint

fn cmp(&self, other: &Fingerprint) -> 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,

Restrict a value to a certain interval.

impl PartialEq for Fingerprint

fn eq(&self, other: &Fingerprint) -> 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 PartialOrd for Fingerprint

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl StableOrd for Fingerprint

const CAN_USE_UNSTABLE_SORT: bool = true

const THIS_IMPLEMENTATION_HAS_BEEN_TRIPLE_CHECKED: () = ()

Marker to ensure that implementors have carefully considered whether their Ord implementation obeys this trait’s contract.

impl Copy for Fingerprint

impl Eq for Fingerprint

impl StructuralPartialEq for Fingerprint

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
