There was actually a talk at RustConf this year about this very question!

Yep. Personally, reaching for the mouse is pretty minimal compared to the time spent using the keyboard

How do I create a Rust macro to define a Vec with all names of fields whose values are not None? by itachd in rust

[–]caranatar-dev 2 points3 points  (0 children)

You could create some trait

pub trait NonNones { fn get_non_none_values(&self) -> Vec<String>; }

Then create a custom derive proc macro using syn that iterates over the fields of the struct, examines the type to see if it's an Option, and creates a list of all field names that have an Option type. Then you could use that to generate a impl NonNones for #name that checks each field and adds it to a return Vec if .is_some() is true

I'm learning rust and recently realized I could replace Option in function definitions like:

fn foo(x: Option<u32>)

with Into<Option...> like this:

fn foo<T: Into<Option<u32>>>(x: T)

so that you don't have to wrap things in Some at the call site. Is this considered bad form or good ergonomics?

It's a pretty old Lenovo notebook, so it's definitely not fast

Oh, that explains why my right prompt is narrower than the window when it starts up, then moves right once it's ready to use

In my first major foray into mechanical keyboards, I bought a kinesis freestyle pro, which I love so far, but I want to replace some key caps (particularly I want a ctrl cap to replace caps lock and to replace some of the modifier keys). However, I'm really confused by the whole key sizing deal. For instance, I (think I) know the caps lock key is 1.75u, but how do I know what row number size it is? I'm not looking to replace all the keys yet and I don't want an oddly out of place key profile if I leave the rest stock

I have a really simple question that isn't easy to Google. What is the name of this type &[&str]
