Enum TrimMethod

pub enum TrimMethod {
    MaxLen(u64),
    MinId(StreamId),
}

Trimming method

Variants

MaxLen(u64)

Request to clean exceeding specified number of elements.

MinId(StreamId)

Request to clean entries below specified id.

Supported since Redis 6.2

Trait Implementations

impl Clone for TrimMethod

fn clone(&self) -> TrimMethod

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TrimMethod

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

Formats the value using the given formatter.

impl ToRedisArgs for TrimMethod

fn write_redis_args<W: ?Sized + RedisWrite>(&self, out: &mut W)

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

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.

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).
