Enum redis_ts::TsDuplicatePolicy

pub enum TsDuplicatePolicy {
    Block,
    First,
    Last,
    Min,
    Max,
    Other(String),
}

Different options for handling inserts of duplicate values. Block is the behaviour redis time series was using before preventing all inserts of values older or equal to latest value in series. Fist will simply ignore the new value (as opposed to returning an error), Last will use the new value, Min the lower and Max the higher value.

Trait Implementations

impl Clone for TsDuplicatePolicy

fn clone(&self) -> TsDuplicatePolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TsDuplicatePolicy

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

Formats the value using the given formatter.

impl FromRedisValue for TsDuplicatePolicy

fn from_redis_value(v: &Value) -> RedisResult<Self>

Given a redis Value this attempts to convert it into the given destination type. If that fails because it’s not compatible an appropriate error is generated.

fn from_owned_redis_value(v: Value) -> Result<Self, RedisError>

Given a redis Value this attempts to convert it into the given destination type. If that fails because it’s not compatible an appropriate error is generated.

fn from_redis_values(items: &[Value]) -> Result<Vec<Self>, RedisError>

Similar to from_redis_value but constructs a vector of objects from another vector of values. This primarily exists internally to customize the behavior for vectors of tuples.

fn from_owned_redis_values(items: Vec<Value>) -> Result<Vec<Self>, RedisError>

The same as from_redis_values, but takes a Vec<Value> instead of a &[Value].

fn from_byte_vec(_vec: &[u8]) -> Option<Vec<Self>>

Convert bytes to a single element vector.

fn from_owned_byte_vec(_vec: Vec<u8>) -> Result<Vec<Self>, RedisError>

Convert bytes to a single element vector.

impl PartialEq for TsDuplicatePolicy

fn eq(&self, other: &TsDuplicatePolicy) -> 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 ToRedisArgs for TsDuplicatePolicy

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 is_single_arg(&self) -> bool

Returns an indiciation if the value contained is exactly one argument. It returns false if it’s zero or more than one. This is used in some high level functions to intelligently switch between GET and MGET variants.
