Struct NodeId 

pub struct NodeId { /* private fields */ }

Stable index owned by one immutable crate::GeometryGraph.

A handle carries its graph’s brand. Another builder refuses it (crate::GraphError::ForeignReference) and another graph’s crate::GeometryGraph::get returns None, so a graph that references a node it does not own cannot be built at all rather than being detected later.

Implementations

impl NodeId

pub const fn index(self) -> usize

Zero-based graph index.

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NodeId

impl Debug for NodeId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeId

Available on crate feature serde only.

A node reference reads as an index into the graph payload being read.

It is refused outside a graph payload: a handle carries the brand of the graph that owns it, and only the graph reader knows that graph.

fn deserialize<D>( deserializer: D, ) -> Result<NodeId, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NodeId

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

Formats the value using the given formatter.

impl Eq for NodeId

impl Hash for NodeId

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 Ord for NodeId

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for NodeId

fn partial_cmp(&self, other: &NodeId) -> 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 Serialize for NodeId

Available on crate feature serde only.

A node reference is written as its zero-based index (ADR 0085).

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.
