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;
    fn with_operation(self, operation: &str) -> Result<T>;
    fn with_location(self, file: &str, line: u32) -> Result<T>;
}

Enhanced error context trait for better error propagation

Required Methods

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

Add context to an error

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

where F: FnOnce() -> String,

Add context with a lazy-evaluated closure

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

Add operation context for debugging

fn with_location(self, file: &str, line: u32) -> Result<T>

Add location context for debugging

Dyn Compatibility

This trait is not dyn compatible.

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