   1 //! System bindings for the wasm/web platform
   2 //!
   3 //! This module contains the facade (aka platform-specific) implementations of
   4 //! OS level functionality for wasm. Note that this wasm is *not* the emscripten
   5 //! wasm, so we have no runtime here.
   6 //!
   7 //! This is all super highly experimental and not actually intended for
   8 //! wide/production use yet, it's still all in the experimental category. This
   9 //! will likely change over time.
  10 //!
  11 //! Currently all functions here are basically stubs that immediately return
  12 //! errors. The hope is that with a portability lint we can turn actually just
  13 //! remove all this and just omit parts of the standard library if we're
  14 //! compiling for wasm. That way it's a compile time error for something that's
  15 //! guaranteed to be a runtime error!
