Trait CommandCargoExt 

pub trait CommandCargoExt
where
    Self: Sized,
{
    // Required method
    fn cargo_bin<S: AsRef<str>>(name: S) -> Result<Self, CargoError>;
}

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 assert_cmd::pkg_name;

use std::process::Command;

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

Required Methods

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.

Cargo support:

• >1.94: works
• >=1.91,<=1.93: works with default build-dir
• <=1.92: works

Panic

Panicks if no binary is found

Examples

use assert_cmd::prelude::*;
use assert_cmd::pkg_name;

use std::process::Command;

let mut cmd = Command::cargo_bin(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);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
