Struct bonsaidb::core::connection::Range

pub struct Range<T> {
    pub start: Bound<T>,
    pub end: Bound<T>,
}

A range type that can represent all std range types and be serialized.

This type implements conversion operations from all range types defined in std.

Fields

start: Bound<T>

The start of the range.

end: Bound<T>

The end of the range.

Implementations

impl<T> Range<T>

pub fn after(self, excluded_start: T) -> Range<T>

Sets the start bound of this range to Bound::Excluded with excluded_start. The range will represent values that are Ordering::Greater than, but not including, excluded_start.

pub fn start_at(self, included_start: T) -> Range<T>

Sets the start bound of this range to Bound::Included with included_start. The range will represent values that are Ordering::Greater than or Ordering::Equal to included_start.

pub fn before(self, excluded_end: T) -> Range<T>

Sets the end bound of this range to Bound::Excluded with excluded_end. The range will represent values that are Ordering::Less than, but not including, excluded_end.

pub fn end_at(self, included_end: T) -> Range<T>

Sets the end bound of this range to Bound::Included with included_end. The range will represent values that are Ordering:::Less than or Ordering::Equal to included_end.

pub fn map<U, F>(self, map: F) -> Range<U>

where F: Fn(T) -> U,

Maps each contained value with the function provided.

pub fn map_result<U, E, F>(self, map: F) -> Result<Range<U>, E>

where F: Fn(T) -> Result<U, E>,

Maps each contained value with the function provided. The callback’s return type is a Result, unlike with map.

pub fn map_ref<U, F>(&self, map: F) -> Range<&U>

where F: Fn(&T) -> &U, U: ?Sized,

Maps each contained value as a reference.

impl Range<Bytes>

pub fn deserialize<T>(&self) -> Result<Range<T>, <T as KeyEncoding>::Error>

where T: for<'k> Key<'k>,

Deserializes the range’s contained values from big-endian bytes.

Trait Implementations

impl<T> Clone for Range<T>

where T: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Range<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for Range<T>

where T: Default,

fn default() -> Range<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Range<T>

where T: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D ) -> Result<Range<T>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<Range<T>> for Range<T>

fn from(range: Range<T>) -> Range<T>

Converts to this type from the input type.

impl<T> From<RangeFrom<T>> for Range<T>

fn from(range: RangeFrom<T>) -> Range<T>

Converts to this type from the input type.

impl<T> From<RangeFull> for Range<T>

fn from(_: RangeFull) -> Range<T>

Converts to this type from the input type.

impl<T> From<RangeInclusive<T>> for Range<T>

where T: Clone,

fn from(range: RangeInclusive<T>) -> Range<T>

Converts to this type from the input type.

impl<T> From<RangeTo<T>> for Range<T>

fn from(range: RangeTo<T>) -> Range<T>

Converts to this type from the input type.

impl<T> From<RangeToInclusive<T>> for Range<T>

fn from(range: RangeToInclusive<T>) -> Range<T>

Converts to this type from the input type.

impl<T> PartialEq for Range<T>

where T: PartialEq,

fn eq(&self, other: &Range<T>) -> 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<T> RangeBounds<T> for Range<T>

fn start_bound(&self) -> Bound<&T>

Start index bound.

fn end_bound(&self) -> Bound<&T>

End index bound.

fn contains<U>(&self, item: &U) -> bool

where T: PartialOrd<U>, U: PartialOrd<T> + ?Sized,

Returns true if item is contained in the range.

impl<T> Serialize for Range<T>

where T: Serialize,

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> Copy for Range<T>

where T: Copy,

impl<T> Eq for Range<T>

where T: Eq,
