Struct ShellOutput

pub struct ShellOutput {
    pub code: Option<i32>,
    pub stdout: Vec<u8>,
    pub stderr: Vec<u8>,
}

Representation of the output of a command executed in an IShell.

The ShellOutput struct holds the results of a command that was run through a shell, including the exit code, standard output, and standard error output.

Examples

use ishell::{IShell, ShellOutput};

let shell = IShell::new();
let shell_output = shell.run_command("true");

// equivalent of `shell_output.code.unwrap() == 0`
assert!(shell_output.is_success());
assert!(shell_output.stdout.is_empty());
assert!(shell_output.stderr.is_empty());

use ishell::{IShell, ShellOutput};

let shell = IShell::new();
let result = shell.run_command("echo 'Hello, world!'");

assert!(result.is_success());

let target_result =
   String::from_utf8(result.stdout).expect("Stdout contained invalid UTF-8!");

assert_eq!(target_result, "Hello, world!");
assert!(result.stderr.is_empty());

Fields

code: Option<i32>

An optional exit code returned by the command.

• If the command executed successfully, this will typically be 0.
• If the command failed or was terminated, this will contain a non-zero value.
• If the command did not return an exit code, this will be None.

stdout: Vec<u8>

A vector of bytes containing the standard output produced by the command.

• This field captures any output that the command printed to the standard output stream (if any).

stderr: Vec<u8>

A vector of bytes containing the standard error output produced by the command.

• This field captures any error messages or diagnostics that the command printed to the standard error stream.

Implementations

impl ShellOutput

pub fn is_success(&self) -> bool

Check if output indicates a command was successful

The check is done by comparing to 0. If no output is found, returns false
