Struct MassCaller 

pub struct MassCaller(/* private fields */);

Names the call site for every integrator call made while it is alive, so the mass.identity line can say WHO paid for the integral rather than leaving a log reader to infer it from the neighbouring profile lines.

Diagnostic only: nothing but the identity line reads it, and the identity line only exists under BREP_PROFILE_MASS_IDENTITY / BREP_PROFILE_MASS_DUMP. The guard restores the previous name on drop so a labelled site nested inside another labelled site reports itself and then hands the outer name back.

Trait Implementations

impl Drop for MassCaller

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
