pub struct MatchDeleteStmt {
pub matches: Vec<Pattern>,
pub where_expr: Option<Expr>,
pub deletes: Vec<EdgeDelete>,
}Expand description
MATCH patterns [WHERE expr] DELETE rel_var [, …]
Each EdgeDelete carries the etype, src node var, and dst node var resolved
from the MATCH patterns at parse time so the executor can emit a read query
returning node keys without extra pattern-scanning.
