Expand description

Possible errors while parsing `Authorization` header.

Should not be used directly unless you are implementing your own authentication scheme.

## Variants§

§

### Invalid

Header value is malformed.

§

### MissingScheme

Authentication scheme is missing.

§

### MissingField(&'static str)

Required authentication field is missing.

§

### ToStrError(ToStrError)

Unable to convert header into the str.

§

### Base64DecodeError(DecodeError)

Malformed base64 string.

§

### Utf8Error(Utf8Error)

Malformed UTF-8 string.
