ScalarQueryOpts

Struct ScalarQueryOpts 

Source
pub struct ScalarQueryOpts<'a> {
    pub filters: &'a [ValueFilter<'a>],
    pub sort: Option<(&'a [u8], bool)>,
    pub distinct: Option<&'a [u8]>,
    pub facets: &'a [Vec<u8>],
    pub offset: usize,
}
Expand description

Everything a scalar RANGE/EQ query carries beyond its bounds and limit — the embedded twin of the wire’s optional clauses. ScalarQueryOpts::default is the plain query.

Fields§

§filters: &'a [ValueFilter<'a>]

FILTER …: non-scoring predicates over stored values, ANDed. A row without the stored value fails — absent is not a value.

§sort: Option<(&'a [u8], bool)>

SORT <field> ASC|DESC: order the page by a stored value; a row with no usable value sorts last in both directions.

§distinct: Option<&'a [u8]>

DISTINCT <field>: at most one row per coerced value; a row with no value is its own group.

§facets: &'a [Vec<u8>]

FACET <field…>: count each field’s values over the whole match set (FILTER reduces the counts; DISTINCT does not).

§offset: usize

OFFSET n: rows to skip before limit takes effect.
