We need Soapy…but for Rust

What is Seify?

  • Solves similar problems as Soapy and gr-osmosdr
  • Seife: German for soap
  • HW abstractions the Rust way
  • RIIR: Rewrite it in Rust :-)
  • FutureSDR HW driver
  • Typed
  • … an invitation to collaborate

Soapy is Great!

  • Soapy API = Seify API
  • Device Args/Filter
  • Key-value dictionaries
  • Supports every type that implements the FromStr trait
  • Serde support

…but also

  • Levels of indirection�libusb → hw driver → soapy driver → soapy (→ soapy-sys → soapy-rs)
  • System-wide installation of modules, i.e., you usually want to have many installed → so does your package manager
  • Problems with some modules

Seify

  • Zero installation for pure Rust drivers
  • Supports Soapy (will hopefully phase-out in the future)
  • Enable only the SDR drivers you need selectively per binary

​

​

  • At the moment, no modules. (Not a priority right now.)

Typed Interface vs Dynamic Dispatch

  • Soapy is dynamic dispatch only
  • Seify supports both (generic device can still be downcasted)
  • The typed interface can be compiled away
  • There should be no reason not to use Seify
