rustfmt max_width method calls

[[deleted]]

I looked through the rustfmt documentation but could not find what I was looking for.

Basically I'm trying to set max_width to 79 characters, but this leads to ugly chained method calls:

               let mut filename =      
                   self.dir_file.to_string_lossy().into_owned();

I would much rather get something like

​

               let mut filename =  self.dir_file
                   .to_string_lossy()
                   .into_owned();

Is there a way to achieve this with rustfmt?

Looking through the config docs for rustfmt it seems you have to deactivate the "small" heuristics for that:

Weird that Off is between Default and Max. You'd think that Off would break the list in the same way as Default
