Expand description

Create a Command for a bin in the Cargo project.

CommandCargoExt is an extension trait for Command to easily launch a crate’s binaries.

See the cargo module documentation for caveats and workarounds.

§Examples

use assert_cmd::prelude::*;

use std::process::Command;

let mut cmd = Command::cargo_bin(env!("CARGO_PKG_NAME"))
    .unwrap();
let output = cmd.unwrap();
println!("{:?}", output);

Required Methods§

source

fn cargo_bin<S: AsRef<str>>(name: S) -> Result<Self, CargoError>

Create a Command to run a specific binary of the current crate.

See the cargo module documentation for caveats and workarounds.

The Command created with this method may run the binary through a runner, as configured in the CARGO_TARGET_<TRIPLET>_RUNNER environment variable. This is useful for running binaries that can’t be launched directly, such as cross-compiled binaries. When using this method with cross, no extra configuration is needed.

§Examples

use assert_cmd::prelude::*;

use std::process::Command;

let mut cmd = Command::cargo_bin(env!("CARGO_PKG_NAME"))
    .unwrap();
let output = cmd.unwrap();
println!("{:?}", output);

use assert_cmd::prelude::*;

use std::process::Command;

let mut cmd = Command::cargo_bin("bin_fixture")
    .unwrap();
let output = cmd.unwrap();
println!("{:?}", output);
