Library and server for dissemination of images obtained from the world server.
|
||||
Library and server for dissemination of images obtained from the world server.
|
||||
|
||||
Currently uses TCP to stream images from the world server. Images are saved temporarily for testing purposes.
|
||||
|
||||
## Development
|
||||
|
||||
For development, you must first have Rust installed. This can be done by following the instructions found at [https://rustup.rs/](https://rustup.rs/). Once this is done, clone this repository, and in the root folder of the repository, run `cargo build --release`. This will both build the dependencies, install the correct toolchains, and create a final executable.
|
||||
|
||||
## Testing
|
||||
|
||||
To test this, first download the `comms-testing` branch of the World Server repository, open the `tennis` project, and run the project. Once this is done, build the latest version of this repository, as mentioned above. Finally, run this project, using `cargo run`.
