What it does

Suggest the use of Result::unwrap_or_else over Result::map_or_else if map_or_else is just used to unpack a successful result while handling an error.

Categories (optional)

What is the advantage of the recommended code over the original code

Code will be shorter (and cleaner).

Drawbacks

None.

Example

.map_or_else(
    |e| handle_the_error(e),
    |n| n,
)

Could be written as:

.unwrap_or_else(|e| handle_the_error(e))
