The first thing I wanted was my own custom error types. Having a centralized error type means I can do things like report errors to external services, show popups, and enforce consistent error handling across the app. By re-exporting Result with my own error type baked in, every new function is forced to handle errors in a way that fits my app's conventions.
That principle underpins Billy Loo’s PHASER (Pluridirectional High-energy Agile Scanning Electron Radiotherapy) system, developed at Stanford and SLAC and licensed to a startup called TibaRay. An array of high-efficiency linacs generates X-ray beams from many directions at once. Their high output overcomes the inefficiency of electron-to-photon conversion to deliver the dose at FLASH speed. Beam convergence at the tumor and electronic shaping conform the dose in three dimensions, producing uniform coverage with relatively simple infrastructure.
