Trait Implementations

impl AsyncReadThrift for KeyValue

fn stream_from_in_protocol<'life0, 'async_trait, T>(
    i_prot: &'life0 mut T
) -> Pin<Box<dyn Future<Output = Result<KeyValue, Error>> + Send + 'async_trait, Global>>where
    'life0: 'async_trait,
    T: 'async_trait + TInputStreamProtocol,

impl Clone for KeyValue

fn clone(&self) -> KeyValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyValue

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

Formats the value using the given formatter.

impl Hash for KeyValue

fn hash<__H>(&self, state: &mut __H)where
    __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for KeyValue

fn cmp(&self, other: &KeyValue) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<KeyValue> for KeyValue

fn eq(&self, other: &KeyValue) -> 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 PartialOrd<KeyValue> for KeyValue

fn partial_cmp(&self, other: &KeyValue) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl ReadThrift for KeyValue

fn read_from_in_protocol<T>(i_prot: &mut T) -> Result<KeyValue, Error>where
    T: TInputProtocol,
