rust: error: `impl Debug` for `Error` with `errname()` integrationrust-6.5
Integrate the `Error` type with `errname()` by providing a new
`name()` method.
Then, implement `Debug` for the type using the new method.
[ Miguel: under `CONFIG_SYMBOLIC_ERRNAME=n`, `errname()` is a
`static inline`, so added a helper to support that case,
like we had in the `rust` branch. Also moved `#include` up
and reworded commit message for clarity. ]
