Don't Unwrap Options: There Are Better Ways

a year ago

Handling `None` in `Option` without `unwrap()` is a common issue in Rust.
The `?` operator doesn't work with `Option` in functions returning `Result`.
Common workarounds include using `unwrap()`, which can lead to runtime panics.
Solutions include changing the return type to `Result`, using `ok_or`, `match`, or `let-else`.
`let-else` (stabilized in Rust 1.65) is recommended for its clarity and robustness.
`anyhow` crate's `context` method is an alternative for applications, not libraries.
`let-else` is preferred for its standard library support, readability, and flexibility.
