Enum ParseUntilErrorBehavior 

pub enum ParseUntilErrorBehavior {
    Consume,
    Stop,
}

When parsing until a given token, sometimes the caller knows that parsing is going to restart at some earlier point, and consuming until we find a top level delimiter is just wasted work.

In that case, callers can pass ParseUntilErrorBehavior::Stop to avoid doing all that wasted work.

This is important for things like CSS nesting, where something like:

foo:is(..) { … }

Would need to scan the whole {} block to find a semicolon, only for parsing getting restarted as a qualified rule later.

Variants

Consume

Consume until we see the relevant delimiter or the end of the stream.

Stop

Eagerly error.
