Struct EdgeId 

pub struct EdgeId(/* private fields */);

Unique identifier for an edge (relationship) in the graph.

EdgeId wraps a u64 and provides type safety to prevent accidentally using an edge ID where an entity ID is expected (or vice versa).

IDs are typically auto-generated by the database when creating edges via [DatabaseTransaction::create_edge], but can also be created manually for bulk loading scenarios.

Example

use manifoldb_core::EdgeId;

let id = EdgeId::new(100);
assert_eq!(id.as_u64(), 100);
println!("{}", id); // Prints: EdgeId(100)

Implementations

impl EdgeId

pub const fn new(id: u64) -> EdgeId

Create a new EdgeId from a raw u64 value.

pub const fn as_u64(self) -> u64

Get the raw u64 value.

Trait Implementations

impl Clone for EdgeId

fn clone(&self) -> EdgeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EdgeId

fn deserialize<__D>( __deserializer: __D, ) -> Result<EdgeId, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EdgeId

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

Formats the value using the given formatter.

impl From<u64> for EdgeId

fn from(id: u64) -> EdgeId

Converts to this type from the input type.

impl Hash for EdgeId

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 EdgeId

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

fn eq(&self, other: &EdgeId) -> 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 EdgeId

fn partial_cmp(&self, other: &EdgeId) -> 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 EdgeId

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.

impl Copy for EdgeId

impl Eq for EdgeId
