Expand your possibilities with the Try ?
Operator
Have you ever found yourself writing a function which may return early based on some condition?
fn my_function() {
// ...
if condition_a {
return;
}
// ...
if condition_b {
return;
}
// ...
}
It doesn't look Rusty, right? This crate offers an extension trait to be able to convert from
a bool
to a ControlFlow
and leverage the mighty power of ?
to get rid of those checks:
use core::ops::ControlFlow;
use try_more::BoolFlow;
fn my_function() -> ControlFlow<()> {
// ...
BoolFlow::r#break(condition_a)?;
// ...
condition_b.r#break()?;
// ...
}
There's also other methods besides continue
and break
which allows to control the value which is passed to the Break
variant.
