# line-protocol
This is an encoder for the influx [line protocol.](https://docs.influxdata.com/influxdb/latest/reference/syntax/line-protocol/)
It has an interface similar to the standard library's `json.Encoder`.
### some caveats.
- It is not concurrency-safe. If you want to make multiple calls to `Encoder.Encode` concurrently you have to manage the concurrency yourself.
- It can only encode values that are uint64, int64, int, float32, float64, string, or bool.
- Ints are converted to int64, float32's to float64.
- If UintSupport is not set, uint64s are converted to int64's and if they are larger than the max int64, they get truncated to the max int64 instead of overflowing.
### Example:
```go
buf := &bytes.Buffer{}
serializer := protocol.NewEncoder(buf)
serializer.SetMaxLineBytes(1024)
serializer.SetFieldTypeSupport(UintSupport)
serializer.Encode(e) // where e is something that implements the protocol.Metric interface
```
