## Examples:
### Features
#### list the features for the latest version
>cargo whatfeatures serde

or

>cargo whatfeatures -p serde
```
serde = 1.0.114
└─ features
  ├─ default
  │ └─ std
  ├─ alloc
  ├─ derive
  ├─ rc
  ├─ std (default)
  └─ unstable
```

The `(default)` will let you easily reference what indv. features are included in the default.

#### list the features and optional deps for the latest version
>cargo whatfeatures serde -v

**Note** this also list 'implied features' (ones that are enabled by other features).
```
serde = 1.0.114
├─ features 
│ ├─ default
│ │ └─ std
│ ├─ alloc
│ ├─ derive
│ │ └─ serde_derive
│ ├─ rc
│ ├─ std (default)
│ └─ unstable
└─ optional dependencies
  └─ serde_derive = =1.0.114
```

#### list the features for a specific version
>cargo whatfeatures -p twitchchat:0.10.2
```
twitchchat = 0.10.2
└─ features
  ├─ default
  │ ├─ async
  │ └─ tokio_native_tls
  ├─ async (default)
  ├─ tokio_native_tls (default)
  └─ tokio_rustls
```

### list the features for a local crate
>cargo whatfeatures --manifest-path .
```
cargo-whatfeatures = 0.9.2
└─ features
  ├─ default
  │ └─ native-tls
  ├─ native-tls (default)
  └─ rustls
```

The command is somewhat smart, if you give it a local directory or the path to a Cargo.toml and it doesn't look like a remote crate, it'll use that. 

So the above could be expressed as `cargo whatfeatures .` or `cargo whatfeatures ~/p/foobar`

`--manifest-path` is a way to ensure it uses the local crate rather than an unfournate similarly named crate on crates.io.

### Simple listing
#### get the latest version
>cargo whatfeatures --short lock-api
```
lock_api = 0.4.1 # 4 weeks ago

using the `-r`, `--restricted` will also list packages that are set to private
>cargo whatfeatures -r ~/dev/godot-rust
