To send data from a Rust app to Axiom, use the Axiom Rust SDK.
The Axiom Rust SDK is an open-source project and welcomes your contributions. For more information, see the GitHub repository.

​
Prerequisites

​
Install SDK

Add the following to your Cargo.toml: 
[dependencies]
axiom-rs = "VERSION"
Replace VERSION with the latest version number specified on the GitHub Releases page. For example, 0.11.0. If you use the Axiom CLI, run eval $(axiom config export -f) to configure your environment variables. Otherwise, create an API token and export it as AXIOM_TOKEN.

​
Use client

use axiom_rs::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Build your client by providing a personal token and an org id:
    let client = Client::builder()
        .with_token("API_TOKEN")
        .build()?;

    // Alternatively, auto-configure the client from the environment variable AXIOM_TOKEN:
    let client = Client::new()?;

    client.datasets().create("DATASET_NAME", "").await?;

    client
        .ingest(
            "DATASET_NAME",
            vec![json!({
                "foo": "bar",
            })],
        )
        .await?;

    let res = client
        .query(r#"['DATASET_NAME'] | where foo == "bar" | limit 100"#, None)
        .await?;
    println!("{:?}", res);

    client.datasets().delete("DATASET_NAME").await?;
    Ok(())
}
