? Operator
Have you ever found yourself writing a function which may return early based on some condition?
```rust 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:
```rust 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.
