Struct Q42RangeQueryPattern 

pub struct Q42RangeQueryPattern {
    pub subject: Option<u64>,
    pub predicate: Option<u64>,
    pub object: Option<u64>,
    pub context: Option<u64>,
}

A simple physical pattern for range-backed Q42 scans. None is an unbound SPARQL position. The planner selects the BIDX object index when object is bound and otherwise performs a bounded sequential block scan.

Fields

subject: Option<u64>

predicate: Option<u64>

object: Option<u64>

context: Option<u64>

Trait Implementations

impl Clone for Q42RangeQueryPattern

fn clone(&self) -> Q42RangeQueryPattern

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Q42RangeQueryPattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for Q42RangeQueryPattern

fn default() -> Q42RangeQueryPattern

Returns the “default value” for a type.

impl PartialEq for Q42RangeQueryPattern

fn eq(&self, other: &Q42RangeQueryPattern) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
