encoding property
The encoding the requester declared, or null if none.
A lenient MIME display string (e.g. application/json). The byte/opaque
encoding is never crystallized into an Encoding object on this field --
it is exposed as a String? display view. Null denotes an absent
encoding (the requester set none), distinct from a present-but-empty
encoding, which reads as an empty string.
Delivered length-carried, so an interior NUL in the rendered MIME string or its schema survives rather than truncating at the seam. Use encodingBytes for the exact data.
Implementation
final String? encoding;
