pub struct KeyValue {
    pub key: String,
    pub value: Option<String>,
}

Wrapper struct to store key values

Fields

key: String

value: Option<String>

Implementations

impl KeyValue

pub fn new<F2>(key: String, value: F2) -> KeyValue where
    F2: Into<Option<String>>, 

pub fn read_from_in_protocol(
    i_prot: &mut dyn TInputProtocol
) -> Result<KeyValue>

pub fn write_to_out_protocol(
    &self,
    o_prot: &mut dyn TOutputProtocol
) -> Result<()>

Trait Implementations

impl Clone for KeyValue

pub fn clone(&self) -> KeyValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyValue

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

Formats the value using the given formatter.

impl Eq for KeyValue

impl Hash for KeyValue

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Ord for KeyValue

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<KeyValue> for KeyValue

pub fn eq(&self, other: &KeyValue) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &KeyValue) -> bool

This method tests for !=.

impl PartialOrd<KeyValue> for KeyValue

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

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

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

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

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

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

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

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

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

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