maflow 0.1.0

Simple Macros, changing the flow of development:

• kill!( flow ) panics
• exit!( flow ) returns ::default()
• next!( flow ) continues
• hold!( flow ) breaks

Flow can be:

1. Option ..!{ inner = option } same as if Some(inner) = option {..}
2. Result ..!{ inner = result } same as if Ok(inner) = option {..}
3. bool ..!{ if bool } same as if 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() returns true if Ok(..) Some(..) or true
• .nay() returns true for the negative counter part
