I observed that in the documentation on docs.rs, certain methods that are specific to non-x86 build targets are not rendered on the documentation page.
The build documentation on docs.rs states that the default compilation target is x86_64-unknown-linux-gnu, which probably leads to the missing documentation for aarch64 specific components.
If I'm not wrong, adding the #[cfg(docsrs)] annotation to all public methods would fix this, as documented here
