maflow
Simple Macros, changing the flow of development:
kill!( flow )
panicsexit!( flow )
returns::default()
next!( flow )
continueshold!( flow )
breaks
Flow can be:
- Option
..!{ inner = option }
same asif Some(inner) = option {..}
- Result
..!{ inner = result }
same asif Ok(inner) = option {..}
- bool
..!{ if bool }
same asif bool {..}
Example
[dependencies]
maflow = "0.1"
use maflow::*;
fn main(){
// Options and Results
let some = Some(true);
kill!{is_true = some} // same as .unwrap()
exit!{is_true = some} // returns default() if None => ()
for i in 0..9 {
next!{is_true = some} // continues if None
hold!{is_true = some} // breaks if None
if is_true {}
}
// Conditional
let is_true = true;
kill!{if is_true} // panics if ..
exit!{if is_true} // returns default() if ..
for i in 0..9 {
next!{if is_true} // continues if ..
hold!{if is_true} // breaks if ..
}
}
Also..
..implements the trait YayNay
for Result
, Option
and bool
with those methods:
.yay()
returnstrue
ifOk(..)
Some(..)
ortrue
.nay()
returnstrue
for the negative counter part
