Trait ErrorContext 

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

Helper trait for adding context to errors

Required Methods

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

Add context to an error result

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

where F: FnOnce() -> String,

Add lazy context to an error result

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
