QuerySpec

Struct QuerySpec 

Source
pub struct QuerySpec {
    pub root: PredicateNode,
    pub search: Option<SearchSpec>,
    pub order_by: Option<OrderBy>,
    pub limit: Option<usize>,
    pub offset: Option<usize>,
    pub count_only: bool,
}

Fields§

§root: PredicateNode§search: Option<SearchSpec>§order_by: Option<OrderBy>§limit: Option<usize>§offset: Option<usize>§count_only: bool

The caller wants matched and the plan, not the page: QueryResult::keys comes back empty and no page is ordered, so a binding has nothing to load records for. What the TS QueryBuilder.count()/.explain() ask for.

Implementations§

Source§

impl QuerySpec

Source

pub fn new(root: PredicateNode) -> Self

Source

pub fn with_order_by( self, field: impl Into<String>, direction: SortDirection, ) -> Self

Source

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

Source

pub fn with_offset(self, offset: usize) -> Self

Source

pub fn counting(self, count_only: bool) -> Self

Source

pub fn unpaged(&self) -> Self

The same spec with the page window dropped — what an aggregate runs, since limit/offset name a window over the answer, not over the rows an aggregate folds. count_only is dropped with it: an aggregate folds the matched keys one record at a time, so it needs them listed.
