Expand description

Input facts extracted from MIR for the Datafrog solver.

Fields§

§loan_issued_at: Vec<(u32, u32)>

(loan_id, point) — loan was created at this point

§cfg_edge: Vec<(u32, u32)>

(from_point, to_point) — control flow edge

§invalidates: Vec<(u32, u32)>

(point, loan_id) — this point invalidates the loan (drop, reassignment)

§use_of_loan: Vec<(u32, u32)>

(loan_id, point) — the loan (reference) is used at this point

§loan_info: HashMap<u32, LoanInfo>

Loan metadata for error reporting.

§potential_conflicts: Vec<(u32, u32)>

Points where two loans conflict (same place, incompatible borrows).
