This is a Rust client to InfluxDB using the 2.0 API.
Add this to cargo.toml

influxdb2-structmap = "0.2"
influxdb2-derive = "0.1.1"
num-traits = "0.2"

value: f64,

value: 0_f64,
time: chrono::MIN_DATETIME.with_timezone(&chrono::FixedOffset::east(7 * 3600)),

InfluxDB data point doesn't support every data types supported by Rust. So, the derive macro only allows for a subset of data types which is also supported in InfluxDB.
Supported struct field types:
Implemented API
This crate uses reqwest under the
hood. You can choose between native-tls
and rustls
with the features
provided with this crate. native-tls
is chosen as the default, like reqwest
does.
# Usage for native-tls (the default).
influxdb2 = "0.3"
# Usage for rustls.
influxdb2 = { version = "0.3", features = ["rustls"], default-features = false }
This project is still at alpha status and all the bugs haven't been ironed yet. With that said, use it at your own risk and feel free to create an issue or pull request.
