Enum redis_streams::StreamMaxlen

pub enum StreamMaxlen {
    Equals(usize),
    Aprrox(usize),
}

Utility enum for passing MAXLEN [= or ~] [COUNT] arguments into StreamCommands. The enum value represents the count.

Variants

Equals(usize)Aprrox(usize)

Trait Implementations

impl PartialEq<StreamMaxlen> for StreamMaxlen

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

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

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

This method tests for !=.

impl Clone for StreamMaxlen

fn clone(&self) -> StreamMaxlen

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for StreamMaxlen

impl Copy for StreamMaxlen

impl Debug for StreamMaxlen

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

Formats the value using the given formatter.

impl ToRedisArgs for StreamMaxlen

fn write_redis_args<W: ?Sized>(&self, out: &mut W) where
    W: 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.
