Implementations on Foreign Types

impl<T, E: Display> LogError for Result<T, E>

Implementation of LogError for Result<T, E> to simplify the logging of errors for calculations that can fail.

Examples

use scl_lib::LogError;

fn error_fn() -> Result<(), String> {
    Err("Error Message!".to_string())
}

fn success_fn() -> Result<(), String> {
    Ok(())
}

// Writes the error message to the log output
let _ = error_fn().log_err();
// Writes nothing for Ok(()) results
let _ = success_fn().log_err();

fn log_err(self) -> Self
