Most likely
let e = Vec::new()
let f = vec![]
let e = Vec::new()
let f = vec![]
There is a reason the multiple methods detailed above exist. Mostly for random iterator syntax. Such as summing an array or calling collect on an iterator. Most Rust devs probably don't use all of these syntax in a single year or maybe even their careers.
let i = 1;
let j = 1;
print!("i: {:?}\n", !i);
print!("j: {:?}\n", !j);
let v = vec![1, 2, 3];
v[i];
So I'm coming from basically obly TypeScript type system experience but that seems completely ok to me. There are times I make my TS uglier to make it less ambiguous and times I make it more ambiguous to make it more readable. It's unreasonable imo that such a system could universally land on the most readable format even if we could all agree what's most readable. Instead, some cases are going to be tradeoffs so that the more common cases can flow unimpeded.
