}Content of rustfmt.toml:
comment_width = 100
use_small_heuristics = "Max"Expected formatting is that nothing changes. The file is already correctly formatted.
Actual formatting is the following (lines with 100 and 99 characters are wrapped):
/*
0 1 2 3 4 5 6 7 8 9
0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789
*/
fn main() {
// This line has 100 characters ...............................................................9
let connection =
candidate.connect(Duration::from_secs(1)).context("connecting to the device")?;
// This line has 99 characters ...............................................................8
let connection =
candidate.connect(Duration::from_secs(1)).context("connecting to the devic")?;
// This line has 98 characters ..............................................................7
let connection = candidate.connect(Duration::from_secs(1)).context("connecting to the devi")?;
}Maybe it's related to #6180? Or maybe it's how use_small_heuristics = Max is supposed to work since the documentation doesn't say anything.
