Crate wrapp

Add additional functionality to Rust errors using a wrapper.

Example

use wrapp::prelude::*;

#[derive(Debug)]
enum MyError {
   ReadFile,
}

impl std::fmt::Display for MyError {
   fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
      match self {
        MyError::ReadFile => write!(f, "could not read file"),
     }
  }
}

impl std::error::Error for MyError {}

if let Err(e) = std::fs::read_to_string("non_existent_file.txt")
    .map_err(|e| MyError::ReadFile.into_wrapp().with_source(Box::new(e))) {
   eprintln!("{}", e.full_display());
}
