Trait aoko::no_std::functions::ext::OptionExt

pub trait OptionExt<T> {
    fn or_else_some(self, f: impl FnOnce() -> T) -> Self;
}

This trait is to implement some extension functions for Option<T> type.

Required methods

fn or_else_some(self, f: impl FnOnce() -> T) -> Self

Implementations on Foreign Types

impl<T> OptionExt<T> for Option<T>

fn or_else_some(self, f: impl FnOnce() -> T) -> Self

This function is similar to or_else, but convert closure result to Some automatically.

Examples

use aoko::no_std::functions::ext::*;
 
assert_eq!(Some(0), None::<u8>.or_else_some(|| 0));
