Expand description

The SomeErr trait provides a method for converting an Option into a Result by treating Some values as Err and None values as Ok.

Examples

use some_to_err::SomeToErr;

let some: Option<&str> = Some("Error");
let result = some.some_to_err(42);
assert_eq!(result, Err("Error"));

use some_to_err::SomeToErr;

let none: Option<&str> = None;
let result = none.some_to_err(42);
assert_eq!(result, Ok(42));
