//! Example how to use `tokio-console` to debug async tasks `jsonrpsee`.
|
|
//! For further information see https://docs.rs/console-subscriber.
|
|
//!
|
|
//! To run it:
|
|
//! `$ cargo install --locked tokio-console`
|
|
//! `$ RUSTFLAGS="--cfg tokio_unstable" cargo run --example tokio_console`
|
|
//! `$ tokio-console`
|
|
//!
|
|
//! It will start a server on http://127.0.0.1:6669 for `tokio-console` to connect to.
