`lychee_lib::client`:
- Improved documentation.
- Added an log message in `ClientBuilder::client()` when provied user-agent
overrides the one defined in provied custom header.
- Removed unnecessary error handling in `Client::check()` when setting HTTPS
scheme because all failure cases should occur when checking this URL the first
time already.
- Removed unnecessary error handling in `Client::remap()` since
`lychee-lib::remap::Remaps::remap()` doesn't returns a `Result` anymore.
- Fixed potential integer overflow in `Client::check_website()` when the wait
time between retries doubles, by using `std::time::Duration::saturating_mul`
instead.
- Renamed `invalid()` to `validate_url()`.
`lychee_lib::remap`:
- Improved documentation, in particular, clarified (in the comment) that it's
URLs not URIs being remapped.
- Changed `Remaps::remap()` so it takes `&mut Url` instead of `Uri` as its
argument, and doesn't return a `Result` as a result.
- Using `Url` instead of `Uri` because it aligns with the concept of
remapping locations rather than identifiers.
- Mutating the URL directly instead of returning a new one for it's more
straightforward.
- There is no error handling because we don't convert from URL to URI
anymore. Furthermore, this always succeed in the first place so we never
needed error handling.
- Added implementation of `IntoIterator` for `&'a Remaps` and convenience method
of `Remaps::iter`. (Their mutable or moving counterparts are deliberately
avoided because we don't want library users to modify all consume the
remapping rules after its instantiation.)
`lychee_lib::error`:
- Renamed `ErrorKind::InvalidUriRemap` to `InvalidUrlRemap` and improved
its error message.
Changes to other modules are minor and only serves to accompany aforementioned
changes.
Remaps allow mapping from a URI pattern to a different URI.
The syntax is
```
lychee --remap 'https://example.comhttp://127.0.0.1'
```
Some use-cases are
- Testing URIs prior to production deployment
- Testing URIs behind a proxy
Be careful when using this feature because checking every link against a
large set of regular expressions has a performance impact. Also there are no
constraints on the URI mapping, so the rules might contradict with each
other.
Remap rules get applied in order of definition to every input URI.
