Implementations

impl ApplicationReturnStatus

pub fn as_int(self) -> i32

pub fn upstream_name(self) -> &'static str

The upstream C enumerator spelling (Solve_Succeeded, Infeasible_Problem_Detected, …) from IpReturnCodes_inc.h.

This is the name every consumer of Ipopt already keys off — CUTEst status tables, benchmarks/scripts/run_nl_bench.sh, the reference JSONs under benchmarks/*/ipopt_ma57.json — so it is what the CLI prints on its machine-readable Status: line. The Rust Debug name is not interchangeable with it: Debug gives SolveSucceeded, and anything comparing against upstream’s tables would silently never match.
