* Avoid potential panicking in `args::parse` by using `Vec::get` instead of indexing
* Refactor: Simplify `opts::{resolve, install}` API
Many parameters can be shared and put into `opts::Options` intead and
that would also avoid a few `Arc<Path>`.
* Optimize `get_install_path`: Avoid cloning `install_path`
* Optimize `LazyJobserverClient`: Un`Arc` & remove `Clone` impl
to avoid additional boxing
* Optimize `find_version`: Avoid cloning `semver::Version`
* Optimize `GhCrateMeta::launch_baseline_find_tasks`
return `impl Iterator<Item = impl Future<Output = ...>>`
instead of `impl Iterator<Item = AutoAbortJoinHandle<...>>`
to avoid unnecessary spawning.
Each task spawned has to be boxed and then polled by tokio runtime.
They might also be moved.
While they increase parallelism, spawning these futures does not justify
the costs because:
- Each `Future` only calls `remote_exists`
- Each `remote_exists` call send requests to the same domain, which is
likely to share the same http2 connection.
Since the conn is shared anyway, spawning does not speedup anything
but merely add communication overhead.
- Plus the tokio runtime spawning cost
* Optimize `install_crates`: Destruct `Args` before any `.await` point
to reduce size of the future
* Refactor `logging`: Replace param `arg` with `log_level` & `json_output`
to avoid dep on `Args`
* Add dep strum & strum_macros to crates/bin
* Derive `strum_macros::EnumCount` for `Strategy`
* Optimize strategies parsing in `install_crates`
* Fix panic in `install_crates` when `Compile` is not the last strategy specified
* Optimize: Take `Vec<Self>` instead of slice in `CrateName::dedup`
* Refactor: Extract new fn `compute_resolvers`
* Refactor: Extract new fn `compute_paths_and_load_manifests`
* Refactor: Extract new fn `filter_out_installed_crates`
* Reorder `install_crates`: Only run target detection if args are valid
and there are some crates to be installed.
* Optimize `filter_out_installed_crates`: Avoid allocation
by returning an `Iterator`
* Fix user_agent of `remote::Client`: Let user specify it
* Refactor: Replace `UIThread` with `ui::confirm`
which is much simpler.
