Implementations

source

impl<'a, T: HashCommands + ?Sized> HRandField<'a, T>

source

pub fn execute<F>(self) -> Pin<Box<dyn Future<Output = Result<F>> + 'a>>where
F: FromValue,

return a random field from the hash value stored at key.

pub fn count<F>(
 self,
 count: i64
) -> Pin<Box<dyn Future<Output = Result<Vec<F>>> + 'a>>where
 F: FromValue,

If the provided count argument is positive, return an array of distinct fields. The array’s length is either count or the hash’s number of fields (HLEN), whichever is lower.

pub fn count_with_values<F, V>(
 self,
 count: i64
) -> Pin<Box<dyn Future<Output = Result<Vec<(F, V)>>> + 'a>>where
 F: FromValue + 'a,
 V: FromValue + 'a,

The optional WITHVALUES modifier changes the reply so it includes the respective values of the randomly selected hash fields.
