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)
}

Implementations

Limit the results to the first N matching items.

Return the value of N from the matching items.

Limit the search to N items in the list.

Trait Implementations

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

Mutably borrows from an owned value. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

The type returned in the event of a conversion error.

Performs the conversion.
