Cbor enhanced library
Inspired by cbor_event but making use of lifetimes to support zero copy deserialization. In addition several iana tags are supported but need to be activated via feature flags.
Supported tags
| Tag | Description | Implementation notes |
|---|---|---|
| 64-82 | Typed arrays | Either direct transmution for the brave or safe parsing for the cautious |
| 80, 81, 82, 85, 86 | Typed float arrays | Either direct transmution for the brave or safe parsing for the cautious, f16 is only supported in big-endian format |
| 260, 261 | Network address | Direct de/serialization of network address |
| 0, 1, 1001 | DateTime | Directly de/serialize chrono date time types with defined precision |
| 2, 3 | BigInt, BigUint | Directly de/serialize num_bigint BigInt, BigUint |
| 37 | Uuid | Directly de/serialize uuid using uuid crate |
| 35 | Regex | Directly de/serialize regex using regex crate |
| 36 | Mime type | Directly de/serialize mime types using mime crate |
| 103 | Geographic Coordinate | Directly de/serialize geographic coordinates |
Limits
- Infinite strings and bytes are not supported since they require allocation
- f16 LE typed array not supported
Features
- Zero-Copy deserialization
- Support for various iana tags
- custom derive macro for serializing structs
Derive macro
Deriving cbor_protocol enables you to serialize/deserialize a struct into a Map<uint,Value> Where the keys for the map are the property id's. The derive macro requires nightly for posiioned compile error reporting.
#[derive(cbor_protocol, Clone, Eq, PartialEq, Debug)]
#[reserved(5, 6, 7)]
struct BlaStruct {
#[id(1)]
#[default("none")]
name: String,
#[id(2)]
value: i32,
}
