Trait ProblemWhile

pub trait ProblemWhile {
    type WithContext;

    // Required methods
    fn problem_while(self, message: impl ToString) -> Self::WithContext;
    fn problem_while_with<F, M>(self, message: F) -> Self::WithContext
       where F: FnOnce() -> M,
             M: ToString;
}

Convert to Problem if needed and add context to it

Required Associated Types

type WithContext

Required Methods

fn problem_while(self, message: impl ToString) -> Self::WithContext

Add context information

fn problem_while_with<F, M>(self, message: F) -> Self::WithContext

where F: FnOnce() -> M, M: ToString,

Add context information from function call

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.
