Matthias Krüger	cad617bba0	some clippy::performance fixes ... use vec![] instead of Vec::new() + push() avoid redundant clones use chars instead of &str for single char patterns in ends_with() and starts_with() allocate some Vecs with capacity to avoid unneccessary resizing	2021-03-15 10:19:59 +01:00
Aleksey Kladov	add87f5424	Avoid blocking the main loop when editing Cargo.toml ... I've noticed a bunch of "main loop too long" warnings in console when typing in Cargo.toml. Profiling showed that the culprit is `rustc --print cfg` call. I moved it to the background project loading phase, where it belongs. This highlighted a problem: we generally use single `cfg`, while it really should be per crate.	2021-01-18 14:52:12 +03:00
