Struct rain_lang::graph::node::Data

pub struct Data<T>(pub T);

Simple data inside a node

Trait Implementations

impl<T: Hash> CacheBy<Data<T>> for Data<T>

type CacheError = Infallible

Potential error when trying to cache a key type

fn node_to_cache(key: Data<T>) -> Result<Node<Data<T>>, Infallible>

Try to get the node to cache for a given key

impl<T: Clone> Clone for Data<T>

fn clone(&self) -> Data<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Copy> Copy for Data<T>

impl<T: Debug> Debug for Data<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Data<T>

fn default() -> Data<T>

Returns the "default value" for a type.

impl<T> Deref for Data<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> DerefMut for Data<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T: Eq> Eq for Data<T>

impl<T: Hash> Hash for Data<T>

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, 

Feeds a slice of this type into the given [Hasher].

impl<T> NodeData for Data<T>

type Error = Infallible

A possible error in placing an item into a node or deduplicating

type CacheAcceptor = ()

An acceptor for cache entries

fn dedup(&mut self) -> Either<Node<Data<T>>, ()>

Attempt to deduplicate this NodeData, either succeeding or returning a cache entry to place the newly created node in should backlinking succeed.

fn backlink(&mut self, _backlink: Backlink<Self>) -> Result<(), Self::Error>

Backlink this data to the given node. Warning: Any attempt to read the data of backlink in this function will lead to deadlock! Backlinking should not create new nodes if dedup obtains a lock on the cache table!

impl<T: PartialEq> PartialEq<Data<T>> for Data<T>

fn eq(&self, other: &Data<T>) -> bool

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

fn ne(&self, other: &Data<T>) -> bool

This method tests for !=.
