[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ check-pass`
			`//@ run-rustfix`
Improve position named arguments lint underline and formatting names For named arguments used as implicit position arguments, underline both the opening curly brace and either: * if there is formatting, the next character (which will either be the closing curl brace or the `:` denoting the start of formatting args) * if there is no formatting, the entire arg span (important if there is whitespace like `{ }`) This should make it more obvious where the named argument should be. Additionally, in the lint message, emit the formatting argument names without a dollar sign to avoid potentially confusion. Fixes #99907 2022-07-30 04:52:46 +00:00
