Struct CommandSpec 

pub struct CommandSpec { /* private fields */ }

A program invocation with separate arguments and process options.

Implementations

impl CommandSpec

pub fn new(program: impl Into<OsString>) -> Self

Create a specification for program.

pub fn arg(self, arg: impl Into<OsString>) -> Self

Append one argument.

pub fn args<I, S>(self, args: I) -> Self

where I: IntoIterator<Item = S>, S: Into<OsString>,

Append multiple arguments.

pub fn current_dir(self, path: impl Into<PathBuf>) -> Self

Set the child working directory.

pub fn output_capacity(self, lines: usize) -> Self

Set the maximum number of unread lines retained between polls.

A capacity of zero discards all lines while still counting them in ProcessUpdate::dropped_lines.

pub fn program(&self) -> &OsStr

Return the executable name or path.

pub fn arguments(&self) -> impl Iterator<Item = &OsStr>

Iterate over the separate process arguments.

pub fn working_directory(&self) -> Option<&Path>

Return the configured child working directory.

pub fn spawn(&self) -> Result<RunningProcess>

Spawn the child with piped stdout and stderr.

Errors

Returns an I/O error when the process or output-reader threads cannot be spawned.
