Enum Key 

#[non_exhaustive]
pub enum Key<'a> {
    String(String),
    Str(&'a str),
    Usize(usize),
    Isize(isize),
    Pair(Cow<'a, str>, Cow<'a, str>),
    Triple(Cow<'a, str>, Cow<'a, str>, Cow<'a, str>),
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

String(String)

Str(&'a str)

Usize(usize)

Isize(isize)

Pair(Cow<'a, str>, Cow<'a, str>)

Triple(Cow<'a, str>, Cow<'a, str>, Cow<'a, str>)

Implementations

impl<'a> Key<'a>

pub fn pair( value1: impl Into<Cow<'a, str>>, value2: impl Into<Cow<'a, str>>, ) -> Self

pub fn triple( value1: impl Into<Cow<'a, str>>, value2: impl Into<Cow<'a, str>>, value3: impl Into<Cow<'a, str>>, ) -> Self

Trait Implementations

impl<'a> Clone for Key<'a>

fn clone(&self) -> Key<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Key<'a>

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

Formats the value using the given formatter.

impl Display for Key<'_>

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

Formats the value using the given formatter.

impl<'a> From<&'a str> for Key<'a>

fn from(value: &'a str) -> Self

Converts to this type from the input type.

impl From<String> for Key<'_>

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<isize> for Key<'_>

fn from(value: isize) -> Self

Converts to this type from the input type.

impl From<usize> for Key<'_>

fn from(value: usize) -> Self

Converts to this type from the input type.

impl ToRedisArgs for Key<'_>

fn write_redis_args<W>(&self, out: &mut W)

where W: ?Sized + RedisWrite,

This writes the value into a vector of bytes. Each item is a single argument. Most items generate a single item.

fn to_redis_args(&self) -> Vec<Vec<u8>>

This converts the value into a vector of bytes. Each item is a single argument. Most items generate a vector of a single item.

fn describe_numeric_behavior(&self) -> NumericBehavior

Returns an information about the contained value with regards to it’s numeric behavior in a redis context. This is used in some high level concepts to switch between different implementations of redis functions (for instance INCR vs INCRBYFLOAT).

fn num_of_args(&self) -> usize

Returns the number of arguments this value will generate.
