||||
|
||||
## Added
|
||||
|
||||
- `EcssEnumerationExt` trait which implements `Debug`, `Copy`, `Clone`,

||||
`PartialEq` and `Eq` in addition to `EcssEnumeration`
|
||||
|
||||
## Changed
|
||||
|
||||
- `EcssEnumeration` trait: Rename `write_to_bytes`
|
||||
to `write_to_be_bytes`
|
||||
|
||||
