This library allows the creation of custom shotover transforms.

There are two consumers of this library:

Custom Transforms

To create a custom transform you need to implement these traits:

• transforms::TransformConfig - Defines what configuration fields the transform has in the topology.yaml.
• transforms::TransformBuilder - Defines how to build the Transform for a new incoming connection. Only one instance is created over shotovers runtime.
• transforms::Transform - Defines the transformation logic of the transform. A new instance is created per incoming connection.

Simple transforms can implement all of these onto a single struct but generally you need seperate structs for each.

The shotover binary

All custom transforms the user wants to use are statically compiled into a single binary. The crate for this binary is very simple, it just consists of a main.rs like:

shotover::import_transform!(transform_crate::TransformConfig);

fn main() {
    shotover::runner::Shotover::new().run_block();
}
