Because decorating an error with more information should not
|
|
|
|
|
let you jump through hoops, `chainerror` has a quick macro for that.
|
|
|
|
|
|
|
|
|
|
`mstrerror!()` fits right into `.map_err()` letting you quickly add
|
|
|
|
|
more debug strings.
|
|
|
|
|
|
|
|
|
|
`mstrerror!()` even understands `format!()` syntax like `println!()`.
