If there is a method call chain, and just one call exceeds max_width, it seems like rustfmt gives up and doesn't format anything.
Example:
fn f() {
foo("This text is under the max_width limit, and shouldn't cause any problems on its own.").long("But this line is extra long, and doesn't fit within 100 max_width. 1234567890123456789").baz().collect().unwrap();
}No format changes will be applied to this. I'm also a bit surprised that error_on_line_overflow does not complain.
I would expect it to wrap each call chain element, even if one of them is too long, such as:
fn f() {
foo("This text is under the max_width limit, and shouldn't cause any problems on its own.")
.long("But this line is extra long, and doesn't fit within 100 max_width. 1234567890123456789")
.baz()
.collect()
.unwrap();
}All default settings.
