Struct ConvexTimingStatistics 

pub struct ConvexTimingStatistics {
    pub overall_alg: TimedTask,
    pub extraction: TimedTask,
    pub presolve: TimedTask,
    pub solve: TimedTask,
    pub solution_recovery: TimedTask,

}

Wall-clock phase accumulator for the dedicated convex (LP / QP / conic) path, the counterpart of TimingStatistics for a solve that has no callbacks, no Hessian updates and no filter line search to attribute time to.

gh #767: print_timing_statistics=yes was accepted on the convex path, reported (used) by print_user_options, and emitted nothing — so a tool attributing cost by phase read 0% everywhere on a convex-routed instance, which is indistinguishable from “already fast” rather than “not measured”. A 9.8 s bearing_400 printed no timer at all.

The rows this reports are the phases the convex path actually has. Four of them — OverallAlgorithm and the three LinearSystem* rows — carry the same labels TimingStatistics::report prints, because they are the same quantities; the rest are named for the convex driver’s own stages rather than reusing NLP row names that would always read zero.

Fields

overall_alg: TimedTask

The whole convex driver: extraction through solution recovery. Reported regardless of the detailed-timer switch, matching TimingStatistics::overall_alg.

extraction: TimedTask

Reading the .nl model into the standard-form convex problem.

presolve: TimedTask

Convex presolve plus the matching postsolve lift.

solve: TimedTask

The engine call itself (interior-point or active-set iterations).

solution_recovery: TimedTask

Recovering per-constraint duals and bound multipliers in the original model’s ordering.

linear_system_symbolic_factorization: TimedTask

linear_system_factorization: TimedTask

linear_system_back_solve: TimedTask

Implementations

impl ConvexTimingStatistics

pub fn new() -> Self

pub fn report(&self) -> String

Format the per-phase report, in the row layout TimingStatistics::report uses (label padded to 42 columns, wall seconds right-aligned). Returns a multi-line string ending in a trailing newline so callers can print! it directly.

pub fn set_detailed_enabled(&self, on: bool)

Enable or disable the detailed per-phase timers, mirroring TimingStatistics::set_detailed_enabled and therefore upstream Ipopt’s timing_statistics gating: with the option off, every start() / end() on these tasks is a no-op and the solve pays no clock syscalls for them.

Self::overall_alg is deliberately left enabled, for the same reason it is on the NLP path — upstream’s help text is explicit that the overall algorithm time is unaffected by this option.

Trait Implementations

impl Debug for ConvexTimingStatistics

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

Formats the value using the given formatter.

impl Default for ConvexTimingStatistics

fn default() -> ConvexTimingStatistics

Returns the “default value” for a type.
