input-synthesis library into a binary, which can then be
added as a component into integration tests. The
can then be used to drive this binary. The binary only forwards
the FIDL API calls to the Rust
input_synthesis library code.
This approach is useful in integration tests. The integration tests can not link Rust directly due to external constraints, but can use prebuilt components.
If you can link to Rust code directly, you can use the
library directly too, without this complication.
