While looking at the standard library documentation of std::result::Result I found some trait implementations of From<StreamResult> documented there. These belong to the miniz_oxide crate. I do not think this trait implementation belongs in the standard library documentation.

See https://doc.rust-lang.org/stable/std/result/enum.Result.html#impl-From%3CStreamResult%3E
This is also present in the standard library documentation that rustup installs locally.

The Version string on docs.rust-lang.org is Version 1.56.1 (59eed8a2a 2021-11-01) at the time of writing.

I was told on the #docs-rs discord channel to tag @GuillaumeGomez in this issue.
