Struct sp_runtime::BoundedBTreeSet

pub struct BoundedBTreeSet<T, S>(/* private fields */);
Expand description

Re-export this since it’s part of the API of this crate. A bounded set based on a B-Tree.

B-Trees represent a fundamental compromise between cache-efficiency and actually minimizing the amount of work performed in a search. See BTreeSet for more details.

Unlike a standard BTreeSet, there is an enforced upper limit to the number of items in the set. All internal operations ensure this bound is respected.

Implementations§

§

impl<T, S> BoundedBTreeSet<T, S>
where S: Get<u32>,

pub fn bound() -> usize

Get the bound of the type in usize.

§

impl<T, S> BoundedBTreeSet<T, S>
where T: Ord, S: Get<u32>,

pub fn new() -> BoundedBTreeSet<T, S>

Create a new BoundedBTreeSet.

Does not allocate.

pub fn into_inner(self) -> BTreeSet<T>

Consume self, and return the inner BTreeSet.

This is useful when a mutating API of the inner type is desired, and closure-based mutation such as provided by try_mutate is inconvenient.

pub fn try_mutate( self, mutate: impl FnMut(&mut BTreeSet<T>), ) -> Option<BoundedBTreeSet<T, S>>

Consumes self and mutates self via the given mutate function.

If the outcome of mutation is within bounds, Some(Self) is returned. Else, None is returned.

This is essentially a consuming shorthand Self::into_inner -> ... -> Self::try_from.

pub fn clear(&mut self)

Clears the set, removing all elements.

pub fn try_insert(&mut self, item: T) -> Result<bool, T>

Exactly the same semantics as BTreeSet::insert, but returns an Err (and is a noop) if the new length of the set exceeds S.

In the Err case, returns the inserted item so it can be further used without cloning.

pub fn remove<Q>(&mut self, item: &Q) -> bool
where T: Borrow<Q>, Q: Ord + ?Sized,

Remove an item from the set, returning whether it was previously in the set.

The item may be any borrowed form of the set’s item type, but the ordering on the borrowed form must match the ordering on the item type.

pub fn take<Q>(&mut self, value: &Q) -> Option<T>
where T: Borrow<Q> + Ord, Q: Ord + ?Sized,

Removes and returns the value in the set, if any, that is equal to the given one.

The value may be any borrowed form of the set’s value type, but the ordering on the borrowed form must match the ordering on the value type.

Methods from Deref<Target = BTreeSet<T>>§

1.17.0 · source

pub fn range<K, R>(&self, range: R) -> Range<'_, T>
where K: Ord + ?Sized, T: Borrow<K> + Ord, R: RangeBounds<K>,

Constructs a double-ended iterator over a sub-range of elements in the set. The simplest way is to use the range syntax min..max, thus range(min..max) will yield elements from min (inclusive) to max (exclusive). The range may also be entered as (Bound<T>, Bound<T>), so for example range((Excluded(4), Included(10))) will yield a left-exclusive, right-inclusive range from 4 to 10.

§Panics

Panics if range start > end. Panics if range start == end and both bounds are Excluded.

§Examples
use std::collections::BTreeSet;
use std::ops::Bound::Included;

let mut set = BTreeSet::new();
set.insert(3);
set.insert(5);
set.insert(8);
for &elem in set.range((Included(&4), Included(&8))) {
    println!("{elem}");
}
assert_eq!(Some(&5), set.range(4..).next());
