nim-cbor-serialization

Introduction

nim-cbor-serialization is a library in the nim-serialization family for turning Nim objects into CBOR and back. Features include:

• Efficient coding of CBOR directly to and from Nim data types
• Full type-based customization of both encoding and decoding
• Flavors for defining multiple CBOR serialization styles per Nim type
• Efficient skipping of data items for partial CBOR parsing
• Flexibility in mixing type-based and dynamic CBOR access
• Structured CborValueRef node type for DOM-style access to parsed data
• Flat CborBytes type for passing nested CBOR data between abstraction layers
• RFC8949 spec compliance
• Passes CBORTestVectors
• Customizable parser strictness including support for non-standard extensions
• Well-defined handling of malformed / malicious inputs with configurable parsing limits

Getting started

requires "cbor_serialization"

Create a type and use it to encode and decode CBOR:

import cbor_serialization

type Request = object
  cborrpc: string
  `method`: string

let encoded = Cbor.encode(Request(cborrpc: "2.0", `method`: "name"))
let decoded = Cbor.decode(encoded, Request)

echo decoded.cborrpc
