Expand description
Options for the [LPOS] command
https://redis.io/commands/lpos
Example
use redis::{Commands, RedisResult, LposOptions}; fn fetch_list_position( con: &mut redis::Connection, key: &str, value: &str, count: usize, rank: isize, maxlen: usize, ) -> RedisResult<Vec<usize>> { let opts = LposOptions::default() .count(count) .rank(rank) .maxlen(maxlen); con.lpos(key, value, opts) }

Returns the “default value” for a type. Read more
This writes the value into a vector of bytes. Each item is a single argument. Most items generate a single item. Read more
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. Read more
This converts the value into a vector of bytes. Each item is a single argument. Most items generate a vector of a single item. Read more
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
). Read more
