Struct usereport::command::Command

pub struct Command { /* fields omitted */ }

Run a CLI command and store its stdout.

Example

#[cfg(target_os = "macos")]
let command = Command::new("uname", r#"/usr/bin/uname -a"#)
    .with_title("Host OS")
    .with_timeout(5);
#[cfg(target_os = "linux")]
let command = Command::new("true", r#"/bin/true"#)
    .with_title("Just a successful command")
    .with_timeout(5);
match command.exec() {
    CommandResult::Success {
        command: _,
        run_time_ms: _,
        stdout: stdout,
    } => println!("Command output '{}'", stdout),
    CommandResult::Failed {
        command: _,
        run_time_ms: _,
        stdout: stdout,
    } => println!("Command failed with output '{}'", stdout),
    CommandResult::Timeout {
        command: _,
        run_time_ms: _,
    } => println!("Command timed out"),
    CommandResult::Error {
        command: _,
        reason: reason,
    } => println!("Command errored because {}", reason),
};

Methods

impl Command

pub fn new<T: Into<String>>(name: T, command: T) -> Command

Create new command with default values

pub fn name(&self) -> &str

Get name of command

pub fn command(&self) -> &str

Get command args

pub fn title(&self) -> Option<&str>

Get title of command

pub fn description(&self) -> Option<&str>

Get description of command

pub fn with_title<T: Into<String>>(self, title: T) -> Command

Set title of command

pub fn with_timeout<T: Into<Option<u64>>>(self, timeout_sec: T) -> Command

Set title of command

pub fn with_description<T: Into<String>, S: Into<Option<T>>>(
    self,
    description: S
) -> Command

Set description of command

pub fn with_links<T: Into<Option<Vec<Link>>>>(self, links: T) -> Command

Set Links of command

pub fn exec(self) -> CommandResult

Execute this command; may panic

Standard output and error will be written to a temporary file, because a pipe may only contain up 64 KB data; cf. http://man7.org/linux/man-pages/man7/pipe.7.html.
