Struct Query 

pub struct Query<R: QueryRange> {
    pub partition: u8,
    pub range: R,
    pub limit: Option<usize>,
}

Query specification for retrieving sorted records from a partition.

Fields

partition: u8

Partition to query (required).

range: R

Range of sort keys to query.

limit: Option<usize>

Maximum number of records to return.

Implementations

impl<R: QueryRange> Query<R>

pub fn new(partition: u8, range: R) -> Self

Creates a new query for the given partition.

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

Sets the maximum number of records to return.

If the range is greater than the limit, the query will return the first limit records.

impl Query<RangeFull>

pub fn new_full_range(partition: u8) -> Self
