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) -> 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.

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.

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.

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.

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

Maps each contained value with the function provided.

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.

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

Maps each contained value as a reference.

impl<'a, T> Range<T>

pub fn as_ord_bytes<K>(&'a self) -> Result<Range<Bytes>, T::Error> where
    T: KeyEncoding<'a, K>,
    K: for<'k> Key<'k>, 

Serializes the range’s contained values to big-endian bytes.

impl<'a, B> Range<B> where
    B: AsRef<[u8]>, 

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

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

Trait Implementations
