Crate blockworx_bench 

What a user waits for, on the settled 50×50 grid, as scenarios both the criterion benches (benches/kernel.rs) and the phase breakdown (examples/spans.rs) run — so the number and its breakdown are of the same thing.

• cargo bench -p blockworx-bench times them; -- --save-baseline <name> and -- --baseline <name> compare runs.
• cargo run --release -p blockworx-bench --example spans tallies where each one’s time goes, span by span. The tally is attribution, not timing: the subscriber costs time of its own.

Each scenario is one kernel call as the frame loop makes it, over a container in memory so a commit pays for the rev it writes. Where the call could quietly do nothing — a nudge refused, a drop that moves nothing — its preparation checks that it does not, since it would time nothing.

Structs

Rig

One session under test, and what driving it needs.

Scenario

A call a user waits for, in three parts: what sets it up once, what comes before each one without being part of it, and the call itself.

Constants

BROWSER 🔒

The browser’s canvas on the MBP, in CSS px: what the far-zoom rendering work measured the canvas and the GPU at.

SCENARIOS

Every scenario, in the order they are reported.

SIDE

The grid’s side. 2,500 blocks and 7,550 wires: the scale the region router was built for.

TWO_CELLS 🔒

Two cells to the right: a move that stays clear of the neighbours.

ZOOMED 🔒

The widths, in world px, of the two framings the zoom scenario swaps between — about 20% and 21% on the benches’ 800 px viewport.

Functions

drop_approach 🔒

The press and the moves of a drag. Past the click distance by a pixel first, as a pointer crosses it: the move that starts a drag carries no travel of its own.

drop_ends 🔒

Where this turn’s drag goes: out two cells, then back.

drop_release 🔒

far_out 🔒

A world rect of width about the sheet’s middle, in the viewport’s shape.

frame 🔒

framed_in_browser 🔒

The browser’s canvas, framed at zoom about the sheet’s middle — or the whole sheet fitted (the 10% floor) when None — checked to land there. A framing pads the rect it is given, so the rect is corrected by the zoom the last framing landed at.

nothing 🔒

pan 🔒

A pan a trackpad frame carries, back and forth: the camera moves and nothing else does.
