The compiler team's explanation
Note: this error code is no longer emitted by the compiler.
This error code was replaced by the more generic E0658.
A stability attribute has been used outside of the standard library.
Erroneous code example:
#[stable(feature = "a", since = "b")] // invalid
#[unstable(feature = "b", issue = "none")] // invalid
fn foo(){}These attributes are meant to only be used by the standard library and are rejected in your own crates.
