Using delouse

First, edit your Cargo.toml to add the delouse crate as an optional dependency, and add a new feature ("debug").

[dependencies]
...
delouse = { version = "0", optional = true }
...

[features]
...
debug = ["dep:delouse"]
...

Next, during the startup in your main or similar, put in:

...

async fn main() -> Result<()> {
    #[cfg(feature = "debug")]
    {
        delouse::init().unwrap();
    }

    ...
}

...

Running your program

When building with cargo build or running with cargo run, add an additional --features debug flag to enable delouse.

Using delouse

By default, and due to no toggles existing yet, delouse will bind to 127.0.0.1:7132. The interface is OpenAPI/JSON based, so you can shave that yak how you'd like, but I tend to just use cURL. Here's some commands for bad days:

tokio specific notes

A lot of the surface we need is unstable. The following table is a list of endpoints and required cfg directives.

In the author's very humble opinion, the following .cargo/config.toml settings are encouraged, in the absense of overriding convictions or specific engineering restrictions when running with tokio:

[build]
rustflags = ["--cfg", "tokio_unstable"]

[target.x86_64-unknown-linux-gnu]
rustflags = ["--cfg", "tokio_unstable", "--cfg", "tokio_taskdump"]

If this is not possible, delouse will gracefully degrade and not serve any endpoints which can not be run.
