Trait OkOrProblem 

pub trait OkOrProblem<O> {
    // Required methods
    fn ok_or_problem<P>(self, problem: P) -> Result<O, Problem>
       where P: Into<Problem>;
    fn ok_or_problem_with<F, P>(self, problem: F) -> Result<O, Problem>
       where F: FnOnce() -> P,
             P: Into<Problem>;
}

Extension trait to map Option to Result with Problem

Required Methods

fn ok_or_problem<P>(self, problem: P) -> Result<O, Problem>

where P: Into<Problem>,

fn ok_or_problem_with<F, P>(self, problem: F) -> Result<O, Problem>

where F: FnOnce() -> P, P: Into<Problem>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
