Structured access to the output of `cargo metadata` and `cargo --message-format=json`.
Usually used from within a `cargo-*` executable
See the [cargo book](https://doc.rust-lang.org/cargo/index.html) for
details on cargo itself.
## Examples
```rust
# extern crate cargo_metadata;
# use std::path::Path;
let mut args = std::env::args().skip_while(|val| !val.starts_with("--manifest-path"));
let mut cmd = cargo_metadata::MetadataCommand::new();
let manifest_path = match args.next() {
Some(ref p) if p == "--manifest-path" => {
cmd.manifest_path(args.next().unwrap());
}
Some(p) => {
cmd.manifest_path(p.trim_start_matches("--manifest-path="));
}
None => {}
};
let _metadata = cmd.exec().unwrap();
```
Pass features flags
```rust
# // This should be kept in sync with the equivalent example in the readme.
# extern crate cargo_metadata;
# use std::path::Path;
# fn main() {
use cargo_metadata::{MetadataCommand, CargoOpt};
let _metadata = MetadataCommand::new()
.manifest_path("./Cargo.toml")
.features(CargoOpt::AllFeatures)
.exec()
.unwrap();
# }
```
Parse message-format output:
```
# extern crate cargo_metadata;
use std::process::{Stdio, Command};
use cargo_metadata::Message;
let mut command = Command::new("cargo")
.args(&["build", "--message-format=json-render-diagnostics"])
.stdout(Stdio::piped())
.spawn()
.unwrap();
let reader = std::io::BufReader::new(command.stdout.take().unwrap());
for message in cargo_metadata::Message::parse_stream(reader) {
match message.unwrap() {
Message::CompilerMessage(msg) => {
println!("{:?}", msg);
},
Message::CompilerArtifact(artifact) => {
println!("{:?}", artifact);
},
Message::BuildScriptExecuted(script) => {
println!("{:?}", script);
},
Message::BuildFinished(finished) => {
println!("{:?}", finished);
},
_ => () // Unknown message
}
}
let output = command.wait().expect("Couldn't get cargo's exit status");
