Struct Id

pub struct Id(pub u64);

An integer Id representing a node in the graph. Ids are topologically sorted.

Tuple Fields

0: u64

Implementations

impl Id

pub const MAX: Id

pub const MIN: Id

pub fn group(self) -> Group

The Group of an Id.

pub fn to(self, other: Id) -> IdIter

Similar to self..=other.

pub fn to_bytearray(self) -> [u8; 8]

Convert to a byte array. Useful for indexedlog range query.

pub fn to_prefixed_bytearray(self, prefix: u8) -> [u8; 9]

Similar to to_bytearray, but insert a prefix at the head. Useful for segment queries where level is the prefix.

Trait Implementations

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Id

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Id

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

Formats the value using the given formatter.

impl Hash for Id

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 NotFoundError for Id

fn not_found_error(&self) -> DagError

fn not_found<T>(&self) -> Result<T>

impl Ord for Id

fn cmp(&self, other: &Id) -> 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<u64> for Id

fn eq(&self, other: &u64) -> 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 PartialEq for Id

fn eq(&self, other: &Id) -> 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.

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 Id

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.

type Output = Id

The resulting type after applying the - operator.

fn sub(self, other: u64) -> Id

Performs the - operation.
