-### Project structure
-
-Rust modules should be split into 2 categories: libraries, and user interface. They differ in the way they do error handling.
-
-Libraries should:
-
-- not panic due to external surprises, only due to internal inconsistencies
-- pass errors and surprises they can't handle to the callers instead
-- not silence errors and surprises
-
-User interface modules should:
-
-- try to provide safe values whenever they encounter an error
-- do the logging
-- give libraries the ability to report errors and surprises (e.g. via giving them loggers)
-
-### Style
-
 Code submitted should roughly match the style of surrounding code. Things that will *not* be accepted are ones that often lead to errors:
 
 - skipping brackets `{}` after every `if()`, `else`, and similar

 ### Cargo dependencies
 
-All Cargo dependencies must be selected in the version available in PureOS, and added to the file `debian/control`. Please check with https://software.pureos.net/search_pkg?term=librust .
-
 Dependencies must be specified in `Cargo.toml` with 2 numbers: "major.minor". Since bugfix version number is meant to not affect the interface, this allows for safe updates.
 
 `Cargo.lock` is used for remembering the revisions of all Rust dependencies. It should be updated often, preferably with each bugfix revision, and in a commit on its own:
