Trait ErrorContext 

pub trait ErrorContext<T> {
    // Required methods
    fn with_context<F>(self, f: F) -> Result<T, MetisError>
       where F: FnOnce() -> String;
    fn with_static_context(self, context: &'static str) -> Result<T, MetisError>;
}

Trait for converting errors with additional context

Required Methods

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

where F: FnOnce() -> String,

Add context to an error result

fn with_static_context(self, context: &'static str) -> Result<T, MetisError>

Add static context to an error result

Dyn Compatibility

This trait is not dyn compatible.

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