CBOR

This library implements the RFC7049: Concise Binary Object Representation (CBOR) in Crystal.

WARNING: This library is still a work in progress.

Features

• Full support for diagnostic notation
• Assign a field to a type base on the CBOR tag
• Support for a wide range of IANA CBOR Tags (see below)

Limitations

Maximum Array/String array/Bytes array length

The spec allows for the maximum length of arrays, string arrays and bytes array to be a UInt64.

While this library supports lengths expressed as a UInt64, it must not exceed Int32::MAX.
