* Move to from vec to streams
Previously we collected all inputs in one vector
before checking the links, which is not ideal.
Especially when reading many inputs (e.g. by using a glob pattern),
this could cause issues like running out of file handles.
By moving to streams we avoid that scenario. This is also the first
step towards improving performance for many inputs.
To stay as close to the pre-stream behaviour, we want to stop processing
as soon as an Err value appears in the stream. This is easiest when the
stream is consumed in the main thread.
Previously, the stream was consumed in a tokio task and the main thread
waited for responses.
Now, a tokio task waits for responses (and displays them/registers
response stats) and the main thread sends links to the ClientPool.
To ensure that the main thread waits for all responses to have arrived
before finishing the ProgressBar and printing the stats, it waits for
the show_results_task to finish.
* Return collected links as Stream
* Initialize ProgressBar without length because we can't know the amount of links without blocking
* Handle stream results in main thread, not in task
* Add basic directory support using jwalk
* Add test for HTTP protocol file type (http://)
* Remove deadpool (once again): Replaced with `futures::StreamExt::for_each_concurrent`.
* Refactor main; fix tests
* Move commands into separate submodule
* Simplify input handling
* Simplify collector
* Remove unnecessary unwrap
* Simplify main
* cleanup check
* clean up dump command
* Handle requests in parallel
* Fix formatting and lints

This removes some boilerplate and is arguably better
than handwriting the error handling code for
maintainability and avoid inconsitent functionality
for the error variants.
thiserror is also the de-facto standard for library
error types as of today.
* Reqwest comes with its own request pool, so there's no need in adding
another layer of indirection. This also gets rid of a lot of allocs.
* Remove cache from collector
* Improve error handling and documentation
* Add back test for request caching in single file

- The binary component and library component are separated as two
packages in the same workspace.
- `lychee` is the binary component, in `lychee-bin/*`.
- `lychee-lib` is the library component, in `lychee-lib/*`.
- Users can now install only the `lychee-lib`, instead of both
components, that would require fewer dependencies and faster
compilation.
- Dependencies for each component are adjusted and updated. E.g.,
no CLI dependencies for `lychee-lib`.
- CLI tests are only moved to `lychee`, as it has nothing to do
with the library component.
- `Status::Error` is refactored to contain dedicated error enum,
`ErrorKind`.
- The motivation is to delay the formatting of errors to strings.
Note that `e.to_string()` is not necessarily cheap (though
trivial in many cases). The formatting is no delayed until the
error is needed to be displayed to users. So in some cases, if
the error is never used, it means that it won't be formatted at
all.
- Replaced `regex` based matching with one of the following:
- Simple string equality test in the case of 'false positivie'.
- URL parsing based test, in the case of extracting repository and
user name for GitHub links.
- Either cases would be much more efficient than `regex` based
matching. First, there's no need to construct a state machine for
regex. Second, URL is already verified and parsed on its creation,
and extracting its components is fairly cheap. Also, this removes
the dependency on `lazy-static` in `lychee-lib`.
- `types` module now has a sub-directory, and its components are now
separated into their own modules (in that sub-directory).
- `lychee-lib::test_utils` module is only compiled for tests.
- `wiremock` is moved to `dev-dependency` as it's only needed for
`test` modules.
- Dependencies are listed in alphabetical order.
- Imports are organized in the following fashion:
- Imports from `std`
- Imports from 3rd-party crates, and `lychee-lib`.
- Imports from `crate::*` or `super::*`.
- No glob import.
- I followed suggestion from `cargo clippy`, with `clippy::all` and
`clippy:pedantic`.
