# Inspect Rust Codelab Example

Reviewed on: 2021-07-12

This directory contains the example program for the Inspect Rust Codelab.

## Building

To add this project to your build, append `--with
//examples/diagnostics/inspect/codelab/rust` to the `fx set` invocation.

## Running

The example program consists of a client program that starts the codelab
server and connects to it.  The codelab server implements a service called
"Reverser" that simply reverses strings passed to it.

Each part of the codelab has its own component, and the client program
can be configured to open a specific part.

To run Part 2 of the codelab run the following:
```
$ ffx component run /core/ffx-laboratory:client_part_2 fuchsia-pkg://fuchsia.com/inspect_rust_codelab#meta/client_part_2.cm

//  To view the output
$ fx log --tag inspect_rust_codelab
```

## Testing

Unit tests for the codelab are available in the `inspect_rust_codelab_unittests`
package.

Integration tests are also available in the
`inspect_rust_codelab_integration_tests`
package.

```
$ fx test inspect_rust_codelab_unittests
$ fx test inspect_rust_codelab_integration_tests
```
