Description
By default, rustfmt currently formats the following code
use std::{ReallyLongImportTypeNameOne, ReallyLongImportTypeNameTwo, ReallyLongImportTypeNameThree, ReallyLongImportTypeNameFour};
as
use std::{
ReallyLongImportTypeNameFour, ReallyLongImportTypeNameOne, ReallyLongImportTypeNameThree,
ReallyLongImportTypeNameTwo,
};
it would be nice to have an option to split these imports into multiple lines, with each line respecting the maximum line width:
use std::{ReallyLongImportTypeNameFour, ReallyLongImportTypeNameThree};
use std::{ReallyLongImportTypeNameOne, ReallyLongImportTypeNameTwo};
