Struct devbox_build::Cmd

pub struct Cmd { /* fields omitted */ }

Clone-able variant of std::process::Command with some build specific helper methods

Cloning allows configuring commands with some common arguments and then invoking it with additional arguments/env vars at different places inside the script.

Method of this type are mirroring those of std::process::Command with addition of run and run_result commands for easier use inside of build sript.

Implementations

impl Cmd

pub fn new<S: AsRef<OsStr>>(program: S) -> Self

Constructs a new Cmd for launching the executable at path program

pub fn arg<S: AsRef<OsStr>>(self, arg: S) -> Self

Adds an argument to the list of execution arguments

pub fn args<I, S>(self, args: I) -> Self where
    I: IntoIterator<Item = S>,
    S: AsRef<OsStr>, 

Adds multiple arguments to the list of execution arguments

pub fn env<K: AsRef<OsStr>, V: AsRef<OsStr>>(self, env: K, val: V) -> Self

Sets an environment variable

pub fn run(&self)

Run the command and exit the build with informative panic message.

This is convienece method for calling std::process::Command::status() method on command instance retrieved by command method

pub fn run_result(&self) -> Result<ExitStatus>

Run the command and return it's status.

This is convienece method for calling std::process::Command::status() method on command instance retrieved by command method

pub fn command(&self) -> Command

Build the std::process::Command with args and environment variables set up by methods on this Cmd instance.
