Struct Eid 

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

Internal Edge ID (64 bits) - pure auto-increment

EIDs are dense, sequential identifiers assigned on edge creation. Unlike the previous design, EIDs no longer embed type information. Edge type lookups are done via the edge tables.

Implementations

impl Eid

pub const INVALID: Eid

Sentinel value representing an invalid/null EID.

pub fn new(id: u64) -> Self

Creates a new edge ID from a raw u64 value.

pub fn as_u64(&self) -> u64

Returns the raw u64 value of this EID.

pub fn is_invalid(&self) -> bool

Check if this EID is the invalid sentinel.

Trait Implementations

impl Clone for Eid

fn clone(&self) -> Eid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Eid

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Eid

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

Formats the value using the given formatter.

impl From<Eid> for u64

fn from(eid: Eid) -> Self

Converts to this type from the input type.

impl From<u64> for Eid

fn from(val: u64) -> Self

Converts to this type from the input type.

impl FromStr for Eid

fn from_str(s: &str) -> Result<Self>

Parses an Eid from a numeric string.

type Err = Error

The associated error which can be returned from parsing.

impl Hash for Eid

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 Ord for Eid

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

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

fn partial_cmp(&self, other: &Eid) -> 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.

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 Eid

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&Value> for Eid

type Error = UniError

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.
