Struct Selection 

pub struct Selection {
    pub query: String,
    pub expect: Option<SelectionExpect>,
    pub templates: Vec<Value>,
    pub cardinality: usize,
    pub identities: Vec<String>,
}

§11.8 selection (3.1): the seventh member of the digested core when the plan was derived from an OQX selector — the query and the templates as given (an { oqx } slot intact; never the rewritten tree), the bound, the hit count and the hit ids in result order. A hit that appears or vanishes between plan and execute changes identities, so the digest form is plan_mismatch without re-running anything but the plan.

Fields

query: String

expect: Option<SelectionExpect>

templates: Vec<Value>

cardinality: usize

identities: Vec<String>

Implementations

impl Selection

pub fn to_json(&self) -> Value

{ query, expect?, templates, cardinality, identities }; expect absent when none was given.
