pub enum DhtArcRange<T = DhtLocation> {
    Empty,
    Full,
    Bounded(T, T),
}
Expand description

A variant of DHT arc which is intentionally forgetful of the Agent’s location. This type is used in places where set logic (union and intersection) is performed on arcs, which splits and joins arcs in such a way that it doesn’t make sense to claim that the arc belongs to any particular agent or location.

This type exists to make sure we don’t accidentally intepret the starting point of such a “derived” arc as a legitimate agent location.

§

impl<T> DhtArcRange<T>

pub fn map<U, F>(self, f: F) -> DhtArcRange<U>where F: Fn(T) -> U,

§

pub fn from_bounds(start: T, end: T) -> DhtArcRange<DhtLocation>

pub fn from_start_and_len(start: T, len: u64) -> DhtArcRange<DhtLocation>

pub fn from_start_and_half_len( start: T, half_len: u32 ) -> DhtArcRange<DhtLocation>

Convenience for our legacy code which defined arcs in terms of half-lengths rather than full lengths

pub fn new_generic(start: T, end: T) -> DhtArcRange<T>

§

impl DhtArcRange<u32>

§

impl DhtArcRange<DhtLocation>

pub fn new_empty() -> DhtArcRange<DhtLocation>

Constructor

pub fn to_bounds_grouped(&self) -> Option<(DhtLocation, DhtLocation)>

Represent an arc as an optional range of inclusive endpoints. If none, the arc length is 0

pub fn to_primitive_bounds_detached(&self) -> (Option<u32>, Option<u32>)

Same as to_bounds_grouped, but with the return type “inside-out”

pub fn is_empty(&self) -> bool

Check if this arc is empty.

pub fn is_full(&self) -> bool

Check if this arc is full.

pub fn is_bounded(&self) -> bool

Check if this arc is bounded.

pub fn overlaps(&self, other: &DhtArcRange<DhtLocation>) -> bool

Check if arcs overlap

pub fn overlap_coverage(&self, other: &DhtArcRange<DhtLocation>) -> f64

Amount of intersection between two arcs

pub fn coverage(&self) -> f64

The percentage of the full circle that is covered by this arc.

pub fn length(&self) -> u64

pub fn half_length(&self) -> u32

pub fn to_ascii(&self, len: usize) -> String

Handy ascii representation of an arc, especially useful when looking at several arcs at once to get a sense of their overlap

pub fn to_ascii_with_ops<L, I>(&self, len: usize, ops: I) -> Stringwhere L: Into<Loc8>, I: IntoIterator<Item = L>,

Ascii representation of an arc, with a histogram of op locations superimposed. Each character of the string, if an op falls in that “bucket”, will be represented by a hexadecimal digit representing the number of ops in that bucket, with a max of 0xF (15)
