Struct Range

pub struct Range<V> { /* private fields */ }

A range used to select a slice of a BTree

Implementations

impl<V> Range<V>

pub fn with_bounds<K: Into<Key<V>>>( prefix: K, bounds: (Bound<V>, Bound<V>), ) -> Self

Construct a new Range with the given prefix.

pub fn with_range<K: Into<Key<V>>>(prefix: K, range: Bounds<V>) -> Self

Construct a new Range with the given prefix.

pub fn from_prefix<K: Into<Key<V>>>(prefix: K) -> Self

Construct a new Range with only the given prefix.

pub fn as_ref(&self) -> Range<&V>

Construct an owned Range by borrowing this Range.

pub fn into_inner(self) -> (Key<V>, (Bound<V>, Bound<V>))

Destructure this Range into a prefix and Bounds.

pub fn has_bounds(&self) -> bool

Return false if this Range has only a prefix.

pub fn is_default(&self) -> bool

Return true if this Range is empty.

pub fn len(&self) -> usize

Return the number of columns specified by this Range.

pub fn prepend<I: IntoIterator<Item = V>>(self, prefix: I) -> Self

Construct a new Range by prepending the given prefix to this one.

Trait Implementations

impl<V: Clone> Clone for Range<V>

fn clone(&self) -> Range<V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for Range<K>

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

Formats the value using the given formatter.

impl<V> Default for Range<V>

fn default() -> Self

Returns the “default value” for a type.

impl<V, K: Into<Key<V>>> From<(K, Range<V>)> for Range<V>

fn from(tuple: (K, Bounds<V>)) -> Self

Converts to this type from the input type.

impl<V> From<SmallVec<[V; 32]>> for Range<V>

fn from(prefix: Key<V>) -> Self

Converts to this type from the input type.

impl<C: Collate> OverlapsRange<Range<<C as Collate>::Value>, Collator<C>> for Range<C::Value>

fn overlaps(&self, other: &Range<C::Value>, collator: &Collator<C>) -> Overlap

Check whether self overlaps other according to the given collator.

fn contains(&self, other: &T, collator: &C) -> bool

Check whether other lies entirely within self according to the given collator.

fn contains_partial(&self, other: &T, collator: &C) -> bool

Check whether other lies partially within self according to the given collator.

impl<BV, C> OverlapsValue<Vec<<C as Collate>::Value>, Collator<C>> for Range<BV>

where BV: Borrow<C::Value>, C: Collate, C::Value: Debug,

fn overlaps_value(&self, key: &Vec<C::Value>, collator: &Collator<C>) -> Overlap

Return true if this range overlaps value according to collator.

fn contains_value(&self, value: &T, collator: &C) -> bool

Return true if this range contains value according to collator.

impl<V: PartialEq> PartialEq for Range<V>

fn eq(&self, other: &Range<V>) -> 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.
