Thanks @iago-lito - that's a bug (at least IMO) |
Here the single To fix this, we should filter out the empty statements from the block when checking its emptiness. |

…anxiyn update rustfmt to v1.4.34 Short summary: Various formatting fixes (several const generic related) and introduction of `imports_granularity` config option Long summary copied from changelog: #### Changed - `merge_imports` configuration has been deprecated in favor of the new `imports_granularity` option. Any existing usage of `merge_imports` will be automatically mapped to the corresponding value on `imports_granularity` with a warning message printed to encourage users to update their config files. #### Added - New `imports_granularity` option has been added which succeeds `merge_imports`. This new option supports several additional variants which allow users to merge imports at different levels (crate or module), and even flatten imports to have a single use statement per item. ([PR rust-lang/rustfmt#4634](rust-lang/rustfmt#4634), [PR rust-lang/rustfmt#4639](rust-lang/rustfmt#4639)) See the section on the configuration site for more information https://rust-lang.github.io/rustfmt/?version=v1.4.33&search=#imports_granularity #### Fixed - Fix erroneous removal of `const` keyword on const trait impl ([rust-lang/rustfmt#4084](rust-lang/rustfmt#4084)) - Fix incorrect span usage wit const generics in supertraits ([rust-lang/rustfmt#4204](rust-lang/rustfmt#4204)) - Use correct span for const generic params ([rust-lang/rustfmt#4263](rust-lang/rustfmt#4263)) - Correct span on const generics to include type bounds ([rust-lang/rustfmt#4310](rust-lang/rustfmt#4310)) - Idempotence issue on blocks containing only empty statements ([rust-lang/rustfmt#4627](rust-lang/rustfmt#4627) and [rust-lang#3868](rust-lang/rustfmt#3868)) - Fix issue with semicolon placement on required functions that have a trailing comment that ends in a line-style comment before the semicolon ([rust-lang/rustfmt#4646](rust-lang/rustfmt#4646)) - Avoid shared interned cfg_if symbol since rustfmt can re-initialize the rustc_ast globals on multiple inputs ([rust-lang/rustfmt#4656](rust-lang/rustfmt#4656)) - Don't insert trailing comma on (base-less) rest in struct literals within macros ([rust-lang/rustfmt#4675](rust-lang/rustfmt#4675))

I'm not sure whether this is expected behaviour or not, but the following code:
Is first reformatted as
And only then as
If I need to run
rustfmt
twice in this case, how am I sure that I have run it enough times in other cases? Do I need to repeat everyrustfmt
until the file is stable?The text was updated successfully, but these errors were encountered:
