Fixes 5399
Memoizing expressions lead to cases where rustfmt's stability guarantees
were violated.
This reverts commit a37d3ab0e1c7c05f1a6410fb7ddf5539f0d030f8.
When useing `version=One` rustfmt will treat the leading `r#` as part of
the `UseSegment` used for sorting. When using `version=Two` rustfmt will
ignore the leading `r#` and only consider the name of the identifier
when sorting the `UseSegment`.
* fix(rustfmt): fix struct field formatting with doc comments present
Fixes#5215
* fix review feedbacks
* add unit test without doc comment
* move tests to a seperate file
* add additional test cases
* reintroduce a newline at the of test/souce/structs.rs
Fixes 5270
Previously, rustfmt only checked the `merge_derives` configuration value
to determine if it should merge_derives. This lead to derives being
merged even when annotated with the `rustfmt::skip` attribute.
Now, rustfmt also checks if derives are explicitly being skipped in the
current context via the `rustfmt::skip` attribute.
When struct_field_align_threshold is non-zero and trailing_comma is set to
"Never," struct field separators are omitted between field groups. This issue is
resolved by forcing separators between groups.
Fixes#4791.
A test is included with a minimal reproducible example.
Fixes 5238
A markdown header is defined by a string that starts with `#`.
Previously, rustfmt would wrap long markdown headers when
`wrap_comments=true`. This lead to issues when rendering these headers
in HTML using rustdoc.
Now, rustfmt leaves markdown headers alone when wrapping comments.
Fixes 5157
Doc comments support markdown, but rustfmt didn't previously assign any
semantic value to leading '> ' in comments. This lead to poor formatting
when using ``wrap_comments=true``.
Now, rustfmt treats block quotes as itemized blocks, which greatly
improves how block quotes are formatted when ``wrap_comments=true``.
Fixes 5042
Previously, trailing commas were removed from the last inline comment.
This lead to rustfmt refusing to format code snippets because
the original comment did not match the rewritten comment.
Now, when rustfmt extracts the last inline comment it leaves trailing
separators alone. Rustfmt does not need to remove these separators
because they are commented out.
Fixes 5088
Previously, rustfmt would add a new comment line anytime it reformatted
an itemized block within a comment when ``wrap_comments=true``. This
would lead to rustfmt adding empty comments with trailing whitespace.
Now, new comment lines are only added if the original comment spanned
multiple lines, if the comment needs to be wrapped, or if the comment
originally started with an empty comment line.
