Struct DbId 

pub struct DbId(pub i64);

Database id is a wrapper around i64. The id is an identifier of a database element both nodes and edges. The positive ids represent nodes, negative ids represent edges. The value of 0 is logically invalid (there cannot be element with id 0) and a default.

Tuple Fields

0: i64

Implementations

impl DbId

pub fn as_index(&self) -> u64

Trait Implementations

impl Clone for DbId

fn clone(&self) -> DbId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DbId

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

Formats the value using the given formatter.

impl Default for DbId

fn default() -> DbId

Returns the “default value” for a type.

impl From<DbId> for QueryId

fn from(value: DbId) -> Self

Converts to this type from the input type.

impl Hash for DbId

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 DbId

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

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

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

fn serialized_size(&self) -> u64

fn serialize(&self) -> Vec<u8>

fn deserialize(buffer: &[u8]) -> Result<Self, DbError>

impl StableHash for DbId

fn stable_hash(&self) -> u64

fn add_to_hash(hash: &mut u64, value: u64)

impl Copy for DbId

impl Eq for DbId

impl StructuralPartialEq for DbId
