2 | [![Go Reference](https://pkg.go.dev/badge/github.com/influxdata/line-protocol/v2.svg)](https://pkg.go.dev/github.com/influxdata/line-protocol/v2) | |
3 | ||
4 | This is an encoder for the influx [line protocol.](https://docs.influxdata.com/influxdb/latest/reference/syntax/line-protocol/) | |
5 | ||
6 | It has an interface similar to the standard library's `json.Encoder`. | |
7 | ||
8 | ||
9 | ### some caveats. | |
10 | - It is not concurrency-safe. If you want to make multiple calls to `Encoder.Encode` concurrently you have to manage the concurrency yourself. | |
11 | - It can only encode values that are uint64, int64, int, float32, float64, string, or bool. | |
12 | - Ints are converted to int64, float32's to float64. | |
13 | - 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. | |
14 | ||
15 | ||
16 | ### Example: | |
17 | ```go | |
18 | buf := &bytes.Buffer{} | |
19 | serializer := protocol.NewEncoder(buf) | |
20 | serializer.SetMaxLineBytes(1024) | |
21 | serializer.SetFieldTypeSupport(UintSupport) | |
22 | serializer.Encode(e) // where e is something that implements the protocol.Metric interface | |
23 | ``` |
