Struct P4Command 

pub struct P4Command<'a> { /* private fields */ }

Builder-style interface for running a single p4 command.

Obtain one via P4Cli::command() and chain configuration calls before calling run.

Implementations

impl<'a> P4Command<'a>

pub fn arg(&mut self, arg: impl AsRef<OsStr>) -> &mut Self

Append a single argument.

pub fn args(&mut self, args: &[impl AsRef<OsStr>]) -> &mut Self

Append all arguments from a slice.

pub fn timeout(&mut self, timeout: Duration) -> &mut Self

Maximum wall-clock time the process is allowed to run. When exceeded the process is killed.

pub fn cwd(&mut self, path: impl Into<PathBuf>) -> &mut Self

Working directory for the child process.

pub fn env( &mut self, key: impl Into<OsString>, val: impl Into<OsString>, ) -> &mut Self

Set an environment variable for the child process.

pub fn stdin(&mut self, data: impl Into<Vec<u8>>) -> &mut Self

Provide data to be piped to the child’s stdin.

pub fn run(&mut self) -> Result<P4Output>

Execute the command and collect output.

Stdout and stderr are read concurrently in separate OS threads to prevent pipe-full deadlocks. If a timeout was set, the process is killed once the deadline is reached.
