Trait ErrorContext

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

Extension trait for adding context to errors

Required Methods

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

where F: FnOnce() -> String,

Add context to an error

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

Add context to an error with a static string

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.
