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

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§

source§

impl<T> Range<T>

source

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

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.

source

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

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.

source

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

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.

source

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

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.

source

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

Maps each contained value with the function provided.

source

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

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

source

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

Maps each contained value as a reference.

source§

impl Range<Bytes>

source

pub fn deserialize<T: for<'k> Key<'k>>( &self ) -> Result<Range<T>, <T as KeyEncoding<T>>::Error>

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