Changelog

[Unreleased]

[1.4.32] 2021-01-16

Fixed

  • Indentation now correct on first bound in cases where the generic bounds are multiline formatted and the first bound itself is multiline formatted (#4636)

Install/Download Options

[1.4.31] 2021-01-09

Changed

  • rustc-ap-* crates updated to v697.0.0

Added

  • Support for 2021 Edition #4618)

Install/Download Options

[1.4.30] 2020-12-20

Fixed

  • Last character in derive no longer erroneously stripped when indent_style is overridden to Visual. (#4584)
  • Brace wrapping of closure bodies maintained in cases where the closure has an explicit return type and the body consists of a single expression statement. (#4577)
  • No more panics on invalid code with err and typeof types (#4357, #4586)

Install/Download Options

[1.4.29] 2020-12-04

Fixed

  • Negative polarity on non-trait impl now preserved. (#4566)

Install/Download Options

[1.4.28] 2020-11-29

Changed

  • rustc-ap-* crates updated to v691.0.0
  • In the event of an invalid inner attribute on a cfg_if condition, rustfmt will now attempt to continue and format the imported modules. Previously rustfmt would emit the parser error about an inner attribute being invalid in this position, but for rustfmt's purposes the invalid attribute doesn't prevent nor impact module formatting.

Added

  • group_imports - a new configuration option that allows users to control the strategy used for grouping imports (#4107)

Fixed

  • Formatting of malformed derived attributes is no longer butchered. (#3898, #4029, #4115, #4545)
  • Correct indentation used in macro branches when hard_tabs is enabled. (#4152)
  • Comments between the visibility modifier and item name are no longer dropped. (#2781)
  • Comments preceding the assignment operator in type aliases are no longer dropped. (#4244)
  • Comments between {& operator, lifetime, mut kw, type} are no longer dropped. (#4245)
  • Comments between type bounds are no longer dropped. (#4243)
  • Function headers are no longer dropped on foreign function items. (#4288)
  • Foreign function blocks are no longer dropped. (#4313)
  • where_single_line is no longer incorrectly applied to multiline function signatures that have no where clause. (#4547)
  • matches! expressions with multiple patterns and a destructure pattern are now able to be formatted. (#4512)

Install/Download Options

[1.4.27] 2020-11-16

Fixed

  • Leading comments in an extern block are no longer dropped (a bug that exists in v1.4.26). (#4528)

Install/Download Options

[1.4.26] 2020-11-14

Changed

  • Original comment indentation for trailing comments within an if is now taken into account when determining the indentation level to use for the trailing comment in formatted code. This does not modify any existing code formatted with rustfmt; it simply gives the programmer discretion to specify whether the comment is associated to the else block, or if the trailing comment is just a member of the if block. (#1575, #4120, #4506)

In this example the // else comment refers to the else:

// if comment
if cond {
    "if"
// else comment
} else {
    "else"
}

Whereas in this case the // continue comments are members of their respective blocks and do not refer to the else below.

if toks.eat_token(Token::Word("modify"))? && toks.eat_token(Token::Word("labels"))? {
    if toks.eat_token(Token::Colon)? {
        // ate the token
    } else if toks.eat_token(Token::Word("to"))? {
        // optionally eat the colon after to, e.g.:
        // @rustbot modify labels to: -S-waiting-on-author, +S-waiting-on-review
        toks.eat_token(Token::Colon)?;
    } else {
        // It's okay if there's no to or colon, we can just eat labels
        // afterwards.
    }
    1 + 2;
    // continue
} else if toks.eat_token(Token::Word("label"))? {
    // continue
} else {
    return Ok(None);
}

Fixed

  • Formatting of empty blocks with attributes which only contained comments is no longer butchered.(#4475, #4467, #4452, #4522)
  • Indentation of trailing comments in non-empty extern blocks is now correct. (#4120)

Install/Download Options

[1.4.25] 2020-11-10

Changed

  • Semicolons are no longer automatically inserted on trailing expressions in macro definition arms (#4507). This gives the programmer control and discretion over whether there should be semicolons in these scenarios so that potential expansion issues can be avoided.

Install/Download Options

[1.4.24] 2020-11-05

Changed

  • Block wrapped match arm bodies containing a single macro call expression are no longer flattened (#4496). This allows programmer discretion so that the block wrapping can be preserved in cases where needed to prevent issues in expansion, such as with trailing semicolons, and aligns with updated Style Guide guidance for such scenarios.

Fixed

  • Remove useless deprecated attribute on a trait impl block in the rustfmt lib, as these now trigger errors (rust-lang/rust/#78626)
