Builder for the lpos command

Implementations

source

impl<'a, T: ListCommands + ?Sized> LPos<'a, T>

source

pub fn execute(
self
) -> Pin<Box<dyn Future<Output = Result<Option<usize>>> + 'a>>

Returns the integer representing the matching element, or nil if there is no match.

However, if the COUNT option is given the command returns an array (empty if there are no matches).

source

pub fn rank(self, rank: usize) -> Self

The RANK option specifies the “rank” of the first element to return, in case there are multiple matches.

source

pub fn count(self, num_matches: usize) -> LPosCount<'a, T>

Sometimes we want to return not just the Nth matching element, but the position of all the first N matching elements. This can be achieved using the COUNT option.

source

pub fn max_len(self, len: usize) -> Self

the MAXLEN option tells the command to compare the provided element only with a given maximum number of list items.
