syntactic-for — a syntactic "for" loop Rust macro.
Take the sum of the bit-length of four integer types:
syntactic-for — a syntactic "for" loop Rust macro.
Take the sum of the bit-length of four integer types:
let sum = syntactic_for!{ ty in [ u8, u16, u32, u64 ] {
[$( <$ty>::BITS ),*].into_iter().sum::<u32>()
}};
assert_eq!(sum, 120);
Implement a trait for a set of types:syntactic_for!{ ty in [ u8, u16, u32, u64, u128 ] {$(
impl MyTrait for $ty {
// snip.
}
)*}}
В README есть больше примеров, где такой макрос может пригодиться.👍15🤯2

Если коротко, то проблема ошибок работы с памятью в том, что они добавляют в программу новые пути исполнения, которых нет в исходнике

YAGNI exceptions (перевод)
I'm essentially a believer in You Aren't Gonna Need It — the principle that you should add features to your software — including generality and abstraction — when it becomes clear that you need them, and not before.
However, there are some things which really are easier to do earlier than later, and where natural tendencies or a ruthless application of YAGNI might neglect them. This is my collection so far...

YAGNI exceptions
A list of some exceptions to the principle of “You Ain't Gonna Need It” – that is, times when doing a bit more up front usually pays off.

Folding arguments into the macro
In Rust, you might have written macros to define structs, functions etc. that are similar but not the same. This is a technique that can make these macros nicer in some cases. I’m sure it has been used before, but I haven’t seen it described anywhere yet.
