The easiest way to build and test Trow is by using the Dockerfiles and associated scripts. If you want a local binary, the Trow executable can be copied out of the final image. The only dependency for building Trow in this way is Docker.
Trow is written in Rust. At the moment, we use Rust nightly due to a dependency on the Rocket framework.
To compile Rust locally, first install rustup if you
haven't already. Set the compiler default to nightly with rustup default nightly and run rustup component add rustfmt. Then run rustup update to make sure you're running a version of Rust with
rustfmt component. Now you should be able to run cargo build from the project root and the Trow
binary will be written to /target/debug/trow.
To execute the binary, you can run cargo run, which will first recompile Trow if anything has
changed.
