Trait ErrorContext 

pub trait ErrorContext<T> {
    // Required methods
    fn context(self, msg: &str) -> Result<T>;
    fn with_context<F>(self, f: F) -> Result<T>
       where F: FnOnce() -> String;
}

Extension trait for adding context to errors.

fn context(self, msg: &str) -> Result<T>

Adds context to an error.

fn with_context<F>(self, f: F) -> Result<T>
