pub struct AboveRangeSet { /* fields omitted */ }

Implementations

impl AboveRangeSet

impl Eq for AboveRangeSet

impl EventSet for AboveRangeSet

type EventIter = EventIter

fn new() -> Self

Returns a new AboveRangeSet instance.

fn next_event(&mut self) -> u64

Generates the next event. There should be no extra ranges when calling this.

Examples

use threshold::*;

let mut above_range_set = AboveRangeSet::new();
assert_eq!(above_range_set.next_event(), 1);
assert_eq!(above_range_set.next_event(), 2);

fn add_event(&mut self, event: u64) -> bool

Adds an event to the set. Returns true if it's a new event.

Examples

use threshold::*;

let mut above_range_set = AboveRangeSet::new();

above_range_set.add_event(1);
assert!(above_range_set.is_event(1));
assert!(!above_range_set.is_event(2));

above_range_set.add_event(3);
assert!(above_range_set.is_event(1));
assert!(!above_range_set.is_event(2));
assert!(above_range_set.is_event(3));

above_range_set.add_event(2);
assert!(above_range_set.is_event(1));
assert!(above_range_set.is_event(2));
assert!(above_range_set.is_event(3));

fn add_event_range(&mut self, start: u64, end: u64) -> bool

Adds a range of events to the set.

fn is_event(&self, event: u64) -> bool

Checks if an event is part of the set.

Examples

use threshold::*;

let mut above_range_set = AboveRangeSet::new();
let event = above_range_set.next_event();
assert!(above_range_set.is_event(event));

above_range_set.add_event(3);
assert!(!above_range_set.is_event(2));
assert!(above_range_set.is_event(3));

fn events(&self) -> (u64, Vec<u64>)

Returns all events seen as a tuple. The first component is the highest event seen, while the second is a vector with the exceptions (in no specific order).

Examples

use threshold::*;

let mut above_range_set = AboveRangeSet::new();

above_range_set.add_event(1);
assert_eq!(above_range_set.events(), (1, vec![]));

above_range_set.add_event(3);
assert_eq!(above_range_set.events(), (1, vec![3]));

above_range_set.add_event(2);
assert_eq!(above_range_set.events(), (3, vec![]));

above_range_set.add_event(4);
assert_eq!(above_range_set.events(), (4, vec![]));

above_range_set.add_event(6);
assert_eq!(above_range_set.events(), (4, vec![6]));

fn frontier(&self) -> u64

Returns the frontier (the highest contiguous event seen).

Examples

use threshold::*;

let mut above_range_set = AboveRangeSet::new();
assert_eq!(above_range_set.frontier(), 0);

above_range_set.add_event(1);
assert_eq!(above_range_set.frontier(), 1);

above_range_set.add_event(3);
assert_eq!(above_range_set.frontier(), 1);

above_range_set.add_event(2);
assert_eq!(above_range_set.frontier(), 3);

above_range_set.add_event(4);
assert_eq!(above_range_set.frontier(), 4);

above_range_set.add_event(6);
assert_eq!(above_range_set.frontier(), 4);

fn join(&mut self, other: &Self)

Merges other AboveRangeSet into self.

Examples

use threshold::*;

let mut above_range_set = AboveRangeSet::new();
above_range_set.add_event(1);
above_range_set.add_event(3);
above_range_set.add_event(4);
assert_eq!(above_range_set.events(), (1, vec![3, 4]));

above_range_set.join(&AboveRangeSet::from_event(3));
assert_eq!(above_range_set.events(), (1, vec![3, 4]));

above_range_set.join(&AboveRangeSet::from_event(5));
assert_eq!(above_range_set.events(), (1, vec![3, 4, 5]));

let mut other = AboveRangeSet::new();
other.add_event(2);
