Hm I guess this seems good, though I do wonder if the impl is really more useful sometimes. I wish we could see both, but doesn't seem like that's really possible. @bors r+ rollup though |

Could it show the impl if the current function is already present? I don't know why I'd want to know what the previous method was. |

I don't think that it is possible to show the impl when the current function is already present. According to https://www.git-scm.com/docs/gitattributes#_defining_a_custom_hunk_header it is only possible to define a regex matching the line to use as hunk header. There doesn't seem to be any way to only match it in some cases or customize it. There is a way to specify a completely custom diff command though. |

Git supports a builtin Rust diff driver [1] since v2.23.0 (2019).
It improves the choice of hunk headers in some cases, such as
diffs within methods, since those are indented in Rust within
an `impl` block, and therefore the default diff driver would
pick the outer `impl` block instead (rather than the method
where the changed code is).
For instance, with the default diff driver:
@@ -455,6 +455,8 @@ impl fmt::Write for RawFormatter {

Git supports a builtin Rust diff driver [1] since v2.23.0 (2019).
It improves the choice of hunk headers in some cases, such as
diffs within methods, since those are indented in Rust within
an `impl` block, and therefore the default diff driver would
pick the outer `impl` block instead (rather than the method
where the changed code is).

Git supports a builtin Rust diff driver [1] since v2.23.0 (2019).
It improves the choice of hunk headers in some cases, such as
diffs within methods, since those are indented in Rust within
an `impl` block, and therefore the default diff driver would
pick the outer `impl` block instead (rather than the method
where the changed code is).
For instance, with the default diff driver:

I found this trick at https://tekin.co.uk/2020/10/better-git-diff-output-for-ruby-python-elixir-and-more
Before the hunk headers for changes in methods would refer to the impl:
After the hunk headers refer to the actual function signature:
When the function signature is visible, it will use the function
signature of the previous method as hunk header:
