Available on crate feature redis-bloom only.

Options for the bf_reserve command.

Implementations

impl BfReserveOptions

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

When capacity is reached, an additional sub-filter is created. The size of the new sub-filter is the size of the last sub-filter multiplied by expansion. If the number of elements to be stored in the filter is unknown, we recommend that you use an expansion of 2 or more to reduce the number of sub-filters. Otherwise, we recommend that you use an expansion of 1 to reduce memory consumption. The default expansion value is 2.

pub fn nonscaling(self) -> Self

Prevents the filter from creating additional sub-filters if initial capacity is reached.

Non-scaling filters require slightly less memory than their scaling counterparts. The filter returns an error when capacity is reached.
