Rust continues to top the charts as the most admired and desired language by developers, and in this post, we dive a little deeper into how (and why) Rust is stealing the hearts of developers around the world.
For downsides, i'd like to add that the lack of function overloading and default parameters can be really obnoxious and lead to [stupid ugly garbage].
A funny one i found in the standard library is in time::Duration. Duration::as_nanos() returns a u128, Duration::from_nanos() only accepts a u64. That means you need to explicitly downcast and possibly lose data to make a Duration after any transformations you did.
They cant change from_nanos() to accept u128 instead because that's breaking since type casting upwards has to be explicit too (for some reason). The only solution then is to make a from_nanos_u128() which is both ugly, and leaves the 64 bit variant hanging there like a vestigial limb.
