| # Rust Native API Native API |
| |
| IoTDB uses Thrift as a cross language RPC framework, so access to IoTDB can be achieved through the interface provided by Thrift. |
| This document will introduce how to generate a native Rust interface that can access IoTDB. |
| |
| ## Dependents |
| |
| * JDK >= 1.8 |
| * Rust >= 1.0.0 |
| * thrift 0.14.1 |
| * Linux、Macos or like unix |
| * Windows+bash |
| |
| Thrift (0.14.1 or higher) must be installed to compile Thrift files into Rust code. The following is the official installation tutorial, and in the end, you should receive a Thrift executable file. |
| |
| ``` |
| http://thrift.apache.org/docs/install/ |
| ``` |
| |
| ## Compile the Thrift library and generate the Rust native interface |
| |
| 1. Find the `pom.xml` file in the root directory of the IoTDB source code folder. |
| 2. Open the `pom.xml` file and find the following content: |
| ```xml |
| <execution> |
| <id>generate-thrift-sources-python</id> |
| <phase>generate-sources</phase> |
| <goals> |
| <goal>compile</goal> |
| </goals> |
| <configuration> |
| <generator>py</generator> |
| <outputDirectory>${project.build.directory}/generated-sources-python/</outputDirectory> |
| </configuration> |
| </execution> |
| ``` |
| 3. Duplicate this block and change the `id`, `generator` and `outputDirectory` to this: |
| ```xml |
| <execution> |
| <id>generate-thrift-sources-rust</id> |
| <phase>generate-sources</phase> |
| <goals> |
| <goal>compile</goal> |
| </goals> |
| <configuration> |
| <generator>rs</generator> |
| <outputDirectory>${project.build.directory}/generated-sources-rust/</outputDirectory> |
| </configuration> |
| </execution> |
| ``` |
| 4. In the root directory of the IoTDB source code folder,run `mvn clean generate-sources`. |
| |
| This command will automatically delete the files in `iotdb/iotdb-protocol/thrift/target` and `iotdb/iotdb-protocol/thrift-commons/target`, and repopulate the folder with the newly generated files. |
| The newly generated Rust sources will be located in `iotdb/iotdb-protocol/thrift/target/generated-sources-rust` in the various modules of the `iotdb-protocol` module. |
| |
| ## Using the Rust native interface |
| |
| Copy `iotdb/iotdb-protocol/thrift/target/generated-sources-rust/` and `iotdb/iotdb-protocol/thrift-commons/target/generated-sources-rust/` into your project。 |
