pub fn find_icu_close(rest: &str) -> Option<usize>Expand description
Quote+depth-aware scan from just after a placeholder’s opening {
(rest), used only once emission-side detection (split_template) has
already decided this is an ICU-dispatch placeholder (a , precedes the
naive first }). Depth starts at 1 for the still-open outer brace;
returns the byte offset of the true closing } (depth reaching 0),
None if it never closes.
