drop_ok

• This crate defines DropOk<E> trait and impl for Result.
• DropOk<E> trait has .drop_ok(self) -> Result<(), E> function.
• This is a syntax sugar for .map(|_|()).

Useful scene

```rust fn somefunction() -> Result<(), MyError> match switcher { patterna => sometask1().dropok()? patternb => sometask2().dropok()? patternc => sometask3()? patternd => some_task4() _ => () }

fn sometask1() -> Result { /* abbr */ } fn sometask2<'a>() -> Result<&'a str, MyError> { /* abbr / } fn some_task3() -> Result<() , MyError> { / abbr / } fn some_task4() { / abbr */ } ```

Note

"I don't need it, because ..."

• Yes, your are right to your world.
  • But, I tired to type/see .map(|_|()). So I'm happy with.drop_ok().
