py-coders 1.0.0

A simple set of symmetric encoder/decoder classes for serializing to and from bytearrays.

py-coders

A simple set of symmetric strongly-typed encoder/decoder classes for serializing to and from byte-like objects.

Usage

Coders are meant to have a simple interface:

• Coder.encocde(obj) to serialize objects to a bytes-like object.
• Coder.decode(buf) to deserialize objects from a byte-like object.

Supported Coders

• IdentityCoder - passes bytes through unchanged.
• StringCoder - string objects, supports ascii, utf8, utf16, etc. encodings.
• UInt16Coder, UInt32Coder, UInt64Coder - unsigned 16/32/64 bit integers. (Big-endian)
• JSONCoder - JSON serializable python object
• PickleCoder - Any picklable Python object.
• ProtobufCoder - Google Protobuf objects. Requires protobuf to be installed.

Compression

Any coder can be altered to compress/decompress data. Calling Coder.compressed will return a coder that uses zlib to compress data after serialization and decompress data before deserialization. A level (0-9) can be provided to specify the compression level used.

Potential Future Features

• Stream encode/decode? May be a bit too specialized of a use case.
• Encryption Coders.
