Extension traits on Vec.

Required Associated Types

Required Methods

A shorthand for into_iter().map(f).collect::<Vec<_>>(). For example:

use gazebo::prelude::*;
assert_eq!(vec![1,2,3].into_map(|x| x*x), vec![1,4,9]);

A shorthand for into_iter().map(f).collect::<Result<Vec<_>, _>>(). For example:

use gazebo::prelude::*;
assert_eq!(vec![1,2,3].into_try_map(|x| Ok(x*x)), Ok::<_, bool>(vec![1,4,9]));
assert_eq!(vec![1,2,-3].into_try_map(|x| if x > 0 { Ok(x*x) } else { Err(false) }), Err(false));

This function will be generalised to Try once it has been standardised.
