Struct TripleBgpTerm 

pub struct TripleBgpTerm {
    pub var: String,
    pub term: String,
    pub object: Option<TripleObject>,
}

One position of a BGP triple pattern: either a bound constant term, or a named variable that joins across patterns. A position is treated as a VARIABLE iff var is non-empty; otherwise it is the bound constant carried by the position’s typed field. Variables sharing the same name across patterns are the same join variable.

Fields

var: String

Variable name (e.g. “x”). Non-empty ⇒ this position is an unbound/join variable and the bound fields below are ignored.

term: String

Bound subject/predicate constant (used when this term is in the s/p position and var is empty).

object: Option<TripleObject>

Bound object constant (used when this term is in the o position and var is empty); resource or literal.
