Trait WithContext 

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

Trait for adding context to errors

Required Methods

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

where F: FnOnce() -> ErrorContext,

fn with_simple_context(self, operation: &str) -> Result<T>

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.
