Struct shell_candy::ShellTask

pub struct ShellTask { /* private fields */ }

A ShellTask runs commands and provides a passthrough log handler for each log line.

Examples

use shell_candy::{Result, ShellTaskLog, ShellTask};

fn main() -> Result<()> {
  // Create a task to check the current version of `rustc` that is installed
  let task = ShellTask::new("rustc --version", |line| {
    match line {
      // print all log lines with an "info: " prefix
      ShellTaskLog::Stderr(message) | ShellTaskLog::Stdout(message) => eprintln!("info: {}", &message),
    }
  })?;

  // Run the task
  task.run()?;

  Ok(())
}
