Struct kitsune_p2p_dht::spacetime::Segment

pub struct Segment<O: Offset> {
    pub power: u8,
    pub offset: O,
}

Any interval in space or time is represented by a node in a tree, so our way of describing intervals uses tree coordinates as well: The length of an interval is 2^(power), and the position of its left edge is at (offset * length).

Fields

power: u8

The exponent, where length = 2^power

offset: O

The offset from the origin, measured in number of lengths

Implementations

impl<O: Offset> Segment<O>

pub fn new<OO: Into<O>>(power: u8, offset: OO) -> Self

Constructor

pub fn num_quanta(&self) -> u64

How many quanta does this segment cover?

pub fn absolute_length(&self, topo: &Topology) -> u64

pub fn quantum_bounds(&self, topo: &Topology) -> (O::Quantum, O::Quantum)

Get the quanta which bound this segment

pub fn contains_quantum(&self, topo: &Topology, coord: O::Quantum) -> bool

The segment contains the given quantum coord

pub fn bisect(&self) -> Option<[Self; 2]>

Split a segment in half

impl Segment<SpaceOffset>

pub fn loc_bounds(&self, topo: &Topology) -> (Loc, Loc)

Get the start and end bounds, in absolute Loc coordinates, for this segment

impl Segment<TimeOffset>

pub fn timestamp_bounds(&self, topo: &Topology) -> (Timestamp, Timestamp)

Get the start and end bounds, in absolute Timestamp coordinates, for this segment

Trait Implementations

impl<O: Clone + Offset> Clone for Segment<O>

fn clone(&self) -> Segment<O>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<O: Debug + Offset> Debug for Segment<O>

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

Formats the value using the given formatter.

impl<'de, O> Deserialize<'de> for Segment<O>

where O: Deserialize<'de> + Offset,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<O: Hash + Offset> Hash for Segment<O>

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<O: Ord + Offset> Ord for Segment<O>

fn cmp(&self, other: &Segment<O>) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<O: PartialEq + Offset> PartialEq for Segment<O>

fn eq(&self, other: &Segment<O>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<O: PartialOrd + Offset> PartialOrd for Segment<O>

fn partial_cmp(&self, other: &Segment<O>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
