Struct Witness

pub struct Witness<J> { /* private fields */ }

Trait Implementations

impl<J: Clone> Clone for Witness<J>

fn clone(&self) -> Witness<J>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<J: Debug> Debug for Witness<J>

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

Formats the value using the given formatter.

impl<J: Hash> Hash for Witness<J>

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<J: Jet> Marker for Witness<J>

type CachedData = WitnessData<J>

Precomputed data about the node, such as its type arrow or various Merkle roots.

type Witness = Option<Value>

Type of witness data attached to DAGs of this node type. Typically either Value or NoWitness.

type Disconnect = Option<Arc<Node<Witness<J>>>>

Type of disconnect data attached to DAGs of this node type.

type SharingId = WitnessId

A type which uniquely identifies a node, for purposes of sharing during iteration over the DAG.

type Jet = J

The jet catalogue used with this node type.

fn compute_sharing_id(_: Cmr, _: &WitnessData<J>) -> Option<WitnessId>

Yields the sharing ID for a given type, starting from its CMR and its cached data.

impl<J: Ord> Ord for Witness<J>

fn cmp(&self, other: &Witness<J>) -> 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<J: PartialEq> PartialEq for Witness<J>

fn eq(&self, other: &Witness<J>) -> 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<J: PartialOrd> PartialOrd for Witness<J>

fn partial_cmp(&self, other: &Witness<J>) -> 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.
