|
Just a general note on the serialization philosophy here:
|
|
I prefer cassettes to be human-readable if possible. Yaml serializes
|
|
bytestrings to !!binary, which isn't readable, so I would like to serialize to
|
|
strings and from strings, which yaml will encode as utf-8 automatically.
|
|
All the internal HTTP stuff expects bytestrings, so this whole serialization
|
|
process feels backwards.
|
|
|
|
Serializing: bytestring -> string (yaml persists to utf-8)
|
|
Deserializing: string (yaml converts from utf-8) -> bytestring
