+# Rust Native API
+
+Apache IoTDB provides an official Rust client SDK: [apache/iotdb-client-rust](https://github.com/apache/iotdb-client-rust). It speaks the Thrift RPC protocol (default port 6667). This document covers the **table model** (`TableSession` / `TableSessionPool`, relational SQL dialect); the tree model is documented separately.
+
+## 1. Requirements
+
+- Rust 1.75+
+- Apache IoTDB 2.x — see [COMPATIBILITY.md](https://github.com/apache/iotdb-client-rust/blob/main/COMPATIBILITY.md) for the full server version matrix
+
+## 2. Installation
+
+Once published to crates.io:
+
+```toml
+[dependencies]
+iotdb-client-rust = "0.1"
+```
+
+Until then, use a git dependency:
+
+```toml
+[dependencies]
+iotdb-client = { git = "https://github.com/apache/iotdb-client-rust" }
+```
+
+The import name is `iotdb_client` in both cases.
+
+## 3. Quick start
+
+```rust
+use iotdb_client::{ColumnCategory, Result, TSDataType, TableSession, Tablet, Value};
+
+fn main() -> Result<()> {
+    let mut session = TableSession::builder()
+        .node_urls(&["127.0.0.1:6667"])?
+        .username("root")
+        .password("root")
+        .build()?;
+
+    session.execute_non_query("CREATE DATABASE IF NOT EXISTS demo")?;
+    session.execute_non_query("USE demo")?;
+    session.execute_non_query(
+        "CREATE TABLE IF NOT EXISTS sensors (device_id STRING TAG, temperature DOUBLE FIELD)",
+    )?;
+
+    // Column-major tablet write. columnCategories must NOT include TIME —
+    // the time column is implicit.
+    let mut tablet = Tablet::new_table(
+        "sensors",
+        vec!["device_id".into(), "temperature".into()],
+        vec![TSDataType::String, TSDataType::Double],
+        vec![ColumnCategory::Tag, ColumnCategory::Field],
+    )?;
+    tablet.add_row(
+        1_720_000_000_000,
+        vec![
+            Some(Value::String("dev-1".into())),
+            Some(Value::Double(21.5)),
+        ],
+    )?;
+    session.insert(&tablet)?;
+
+    // Query with row iteration; the dataset borrows the session until dropped.
+    {
+        let mut dataset =
+            session.execute_query("SELECT time, device_id, temperature FROM sensors")?;
+        while let Some(row) = dataset.next_row()? {
+            println!("{:?}", row.values);
+        }
+    }
+
+    session.execute_non_query("DROP DATABASE demo")?;
+    session.close()
+}
+```
+
+## 4. Session pool
+
+`TableSessionPool` is the thread-safe pool variant for concurrent workloads; `acquire()` returns an RAII guard that releases the session back to the pool on drop. See the runnable [`session_pool` example](https://github.com/apache/iotdb-client-rust/blob/main/examples/session_pool.rs).
+
+## 5. TLS & RPC compression
+
+**RPC compression** (the Thrift compact protocol) must match the server setting `dn_rpc_thrift_compression_enable` (default `false`):
+
+```rust
+let mut session = TableSession::builder()
+    .node_urls(&["127.0.0.1:6667"])?
+    .enable_rpc_compression(true)
+    .build()?;
+```
+
+**TLS** is behind the `tls` cargo feature:
+
+```toml
+iotdb-client-rust = { version = "0.1", features = ["tls"] }
+```
+
+```rust
+let mut session = TableSession::builder()
+    .node_urls(&["127.0.0.1:6667"])?
+    .use_ssl(true)
+    .ca_cert_path("ca.pem")
+    .build()?;
+```
+
+## 6. Examples
+
+Full runnable examples live in the repository's [`examples/`](https://github.com/apache/iotdb-client-rust/tree/main/examples) directory:
+
+```sh
+cargo run --example table_session
+cargo run --example session_pool
+```
