That's the wrong repeat(), I was talking about str::repeat(): https://doc.rust-lang.org/std/primitive.str.html#method.repe...

Rust uses `repeat()`, which sounds much more descriptive to me. The types in the function signature make the "clone" part of the name redundant.

Other than that being a terrible name (it's almost impossible to be sure what it does without consulting documentation), I personally do prefer fewer implicit/overloaded operations.

Title should be "PAM", not "Pam".

Qm.n notation is for fixed point numbers, not floating point. As OP said, floating point was not a viable option at the time.

A typo of "compiler", I'm fairly certain.

Wait, what? How could electric resistive heating with its 100% efficiency possibly be less efficient than gas or oil, which are the main alternatives in use at this point? Heat pumps have >100% efficiency, which makes them stand way out

Not just heat pumps, but also electric water heaters, which are standard issue for older apartment buildings (those without central hot water).

While I think shadowing is great for code readability and I've never encountered a bug caused by it, you can always make sure clippy doesn't let you do it by putting a `#![deny(clippy::shadow_reuse, clippy::shadow_same, clippy::sh

> I'd rather program fail at compile than runtime, and rather it fail loudly than quietly. I agree! I was just illustrating the kind of tradeoff that has to be made for that to be possible.

To expand on your float sorting example, sorting a slice[1] in Rust requires the element type to implement the Ord trait, i.e. be totally ordered. Trying to sort a slice of floats will result in a compiler error, even though it might be tot

What kind of primitives are you talking about here? In my experience you don't really have to manually instantiate anything other than a PLL or maybe a multiplier unless you're doing something very specialized.

We'd need an even more unholy name for `unsafe { foo.unwrap_unchecked() }`!

There is a problem here - it's verbose and prone to silent-ish breakage if the surrounding context changes e.g. due to refactors (well, probably not with this tiny example, but I hope you know what I mean). Thankfully, there is also a

Oh yeah, that's indeed not great. For messages with up to ~5 lines, the bridge actually just sends several messages, but as soon as the message has more lines than that, it only shows the first line as a preview. I could've sworn

One big hurdle for C++ programmers learning Rust that I've seen time and time again in various community support channels is fixing their trust issues with the compiler. They are so used to compiler output being useless or worse than u
