[INFO] [stderr]    Compiling xwt v0.18.0 (/opt/rustwide/workdir)
[INFO] [stderr] warning: xwt@0.18.0: This crate provides a simple mapping to one of the drivers depending on the current build target (native vs wasm). For better portability, the `xwt-core` crate should be used instead, and the drivers should be hand-picked for each of the targets instead of using a crate like this one. We will be removing the `xwt` crate soon, and you are free to import `xwt-web-sys` and `xwt-wtransport` manually and put them under a `cfg_if!` macro yourself if you prefer this mode of operation; they key difference there is you maintain explicit control over the your driver dependencies rather than us having to tie them together for you - and this how it should be. See the examples on Github for more info on how we intend for xwt to be used.
