Module observer 

Progress and intermediate outputs reported by pipeline stages as they run.

A stage that produces more than its return value (QSMART’s vessel mask and per-stage local fields and χ, for example) hands each intermediate to an Observer as soon as it exists. The observer gets a borrowed slice, so a host that only wants the final result keeps no extra copies, and a host that wants to show or save an intermediate copies or writes just that one.

Any FnMut(usize, usize) closure is an observer that takes progress and ignores outputs, and &mut () is an observer that ignores both.

Enums

VolumeRef

A borrowed volume reported by a stage: real-valued data or a binary mask, in the stage’s grid (same dimensions and voxel order as its inputs).

Traits

Observer
