# CBOR
|
|
|
|
[](https://builds.sr.ht/~arestifo/crystal-cbor?)
|
|
|
|
This library implements the [RFC7049: Concise Binary Object Representation (CBOR)][rfc]
|
|
in Crystal.
|
|
|
|
## Features
|
|
|
|
- Full RFC7049 support
|
|
- 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
|
|
|
|
## Limitations
|
|
|
|
### Half-precision floating point is not supported
|
|
|
|
Crystal doesn't have a `Float16` type, so half-precision floating point numbers
|
|
are not supported for the time being.
|
|
|
|
### 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`.
|
|
|
|
