Enum Bound 

pub enum Bound<T> {
    Unbounded,
    Included(T),
    Excluded(T),
}

A range bound that can be serialized.

Variants

Unbounded

No bound.

Included(T)

Bounded by the contained value (inclusive).

Excluded(T)

Bounded by the contained value (exclusive).

Implementations

impl<T> Bound<T>

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

Maps the contained value, if any, and returns the resulting Bound.

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

Maps the 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) -> Bound<&U>

Maps each contained value as a reference.

impl Bound<Bytes>

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

Deserializes the bound’s contained value from big-endian bytes.

Trait Implementations

impl<T: Clone> Clone for Bound<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Bound<T>

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

Formats the value using the given formatter.

impl<T> Default for Bound<T>

fn default() -> Self

Returns the “default value” for a type.

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

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a, T> From<&'a Bound<T>> for Bound<&'a T>

fn from(bound: &'a Bound<T>) -> Self

Converts to this type from the input type.

impl<'a, T> From<Bound<&'a T>> for Bound<&'a T>

fn from(bound: Bound<&'a T>) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for Bound<T>

fn eq(&self, other: &Bound<T>) -> 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.

impl<T> Serialize for Bound<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: Copy> Copy for Bound<T>

impl<T: Eq> Eq for Bound<T>

impl<T> StructuralPartialEq for Bound<T>
