[pdm-devel] [PATCH proxmox-yew-comp 15/15] use and_then instead of map(..).flatten(..) on Option

Fixes:

warning: called `map(..).flatten()` on `Option`
  --> src/configuration/network_view.rs:30:10
   |
30 |           .map(|c| c.as_str())
   |  __________^
31 | |         .flatten()
   | |__________________^ help: try replacing `map` with `and_then` and remove the `.flatten()`: `and_then(|c| c.as_str())`
   |
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#map_flatten
   = note: `#[warn(clippy::map_flatten)]` on by default
