pub enum BoundRef<'a, TOwned, TBorrowed = TOwned>where
    TBorrowed: PartialEq + ?Sized,
    TOwned: Borrow<TBorrowed> + PartialEq<TBorrowed>,
    MaybeOwned<'a, TOwned, TBorrowed>: PartialEq,{

    Included(MaybeOwned<'a, TOwned, TBorrowed>),

A range bound reference.

Variants

Unbounded

No bound.

Included(MaybeOwned<'a, TOwned, TBorrowed>)

Bounded by the contained value (inclusive).

Excluded(MaybeOwned<'a, TOwned, TBorrowed>)

Bounded by the contained value (exclusive).

Implementations

impl<'a, TOwned, TBorrowed> BoundRef<'a, TOwned, TBorrowed>where TBorrowed: PartialEq + ?Sized, TOwned: Borrow<TBorrowed> + PartialEq<TBorrowed>,

pub fn as_ord_bytes(&'a self) -> Result<Bound<Bytes>, TBorrowed::Error>where TBorrowed: KeyEncoding<TOwned>, TOwned: for<'k> Key<'k> + Borrow<TBorrowed>,

Serializes the contained value to big-endian bytes.

impl<'a, TOwned, TBorrowed> BoundRef<'a, TOwned, TBorrowed>where TBorrowed: PartialEq + ?Sized, TOwned: Borrow<TBorrowed> + PartialEq<TBorrowed>,

pub const fn borrowed(range: Bound<&'a TBorrowed>) -> Self

Returns a borrowed bound from the bound provided.

pub fn owned(range: Bound<TOwned>) -> Self

Returns an owned bound ref from the bound provided.

pub fn map_result<U, E, F: Fn(&TBorrowed) -> Result<U, E>>( self, map: F ) -> Result<Bound<U>, E>

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

Trait Implementations

impl<'a, TOwned, TBorrowed> Clone for BoundRef<'a, TOwned, TBorrowed>where TBorrowed: PartialEq + ?Sized + Clone, TOwned: Borrow<TBorrowed> + PartialEq<TBorrowed> + Clone, MaybeOwned<'a, TOwned, TBorrowed>: PartialEq,

fn clone(&self) -> BoundRef<'a, TOwned, TBorrowed>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, TOwned, TBorrowed> Debug for BoundRef<'a, TOwned, TBorrowed>where TBorrowed: PartialEq + ?Sized + Debug, TOwned: Borrow<TBorrowed> + PartialEq<TBorrowed> + Debug, MaybeOwned<'a, TOwned, TBorrowed>: PartialEq,

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

Formats the value using the given formatter.

impl<'a, TOwned, TBorrowed> From<&'a BoundRef<'a, TOwned, TBorrowed>> for Bound<&'a TBorrowed>where TBorrowed: PartialEq + ?Sized, TOwned: Borrow<TBorrowed> + PartialEq<TBorrowed>,

fn from(bound: &'a BoundRef<'a, TOwned, TBorrowed>) -> Self

Converts to this type from the input type.

impl<'a, TOwned, TBorrowed> PartialEq<BoundRef<'a, TOwned, TBorrowed>> for BoundRef<'a, TOwned, TBorrowed>where TBorrowed: PartialEq + ?Sized + PartialEq, TOwned: Borrow<TBorrowed> + PartialEq<TBorrowed> + PartialEq, MaybeOwned<'a, TOwned, TBorrowed>: PartialEq,

fn eq(&self, other: &BoundRef<'a, TOwned, TBorrowed>) -> 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.
