Description
"cargo fmt" command does not remove white spaces in derive block. For example i expected this
#[derive(serde :: Serialize)]
enum Something {
Variant
}
to become this
#[derive(serde::Serialize)]
enum Something {
Variant
}
cannot find anything similar in https://rust-lang.github.io/rustfmt/?version=master&search=
tried to find by words "space" or "derive"
(default config)

Research direction
Start by reproducing the example with the cargo fmt command using the default configuration. Investigate how rustfmt handles paths inside derive blocks; done means whitespace around the path separator is formatted from serde :: Serialize to serde::Serialize without changing the surrounding enum.
