Some errors have detailed explanations: E0271, E0277, E0631.
For more information about an error, try `rustc --explain E0271`.
error: could not compile `steamctl` (bin "steamctl") due to 18 previous errors
Using 1 EffectGroup + 1 Effect works though...
Cannot run cargo test due to dependencies of examples
I think those libraries need to be added to dev-dependencies or the example needs to have less dependencies.
Ergonomics of `effing_mad::run` and composition of effect handlers
Currently:
fn main() {
let console_handler = handler!(Console {
print(s, _) => println!("{s}"),
});
let with_console = handle_group(do_command(), console_handler);
let cli_options_handler = handler!(CliOptions {
read() => options().run(),
});
let with_cli_options = handle_group(with_console, cli_options_handler);
effing_mad::run(with_cli_options);
}What if:
fn main() {
let console_handler = handler!(Console {
print(s, _) => println!("{s}"),
});
let cli_options_handler = handler!(CliOptions {
read() => options().run(),
});
effing_mad::run!(
do_command()
|> handle_group(console_handler)
|> handle_group(cli_options_handler)
);
}And mainly because naming is hard... There is nothing special about with_cli_options in the previous code other than it just happens to be the last in the chain?
you have a nice readme
it made me laugh out loud innerly
great work
love it
