Allow Selector to be const-creatable #141
Description
Currently we cannot create const SELECTOR: Selector = ... object, due to Selector::parse not being const.
This in turn would require cssparser::Tokenizer::new() and cssparser::Tokenizer::with_first_line_number() to be const as well.
I think that this would be possible to do.

I am highly sceptical this will be possible soon as this would require things like
selectors::parser::SelectorList::parseto be const.conqp commentedon Sep 3, 2023
Probably. I'm currently using
once_cell::sync::Lazyto work around this limitation.cfvescovo commentedon Feb 29, 2024
OnceCell is now part of the standard library: rust-lang/rfcs#2788
I think this should be considered the solution to this issue, since we cannot make Selector const-creatable
