Struct ProcessSpec 

pub struct ProcessSpec {
    pub program: PathBuf,
    pub args: Vec<OsString>,
    pub dir: Option<PathBuf>,
    pub env: HashMap<String, String>,
    pub env_policy: EnvPolicy,
}

What to execute as a subprocess.

Fields

program: PathBuf

Program name or path to execute.

args: Vec<OsString>

Command-line arguments.

dir: Option<PathBuf>

Working directory for the process.

env: HashMap<String, String>

Environment variables to set.

env_policy: EnvPolicy

Environment inheritance policy.

Implementations

impl ProcessSpec

pub fn new<P: Into<PathBuf>>(program: P) -> Self

Create a new process spec with just a program name.

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

Add a command-line argument.

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

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

Add multiple command-line arguments.

pub fn dir<P: Into<PathBuf>>(self, dir: P) -> Self

Set the working directory.

pub fn env<K: Into<String>, V: Into<String>>(self, key: K, value: V) -> Self

Set an environment variable.

pub fn envs<K: Into<String>, V: Into<String>, I: IntoIterator<Item = (K, V)>>( self, vars: I, ) -> Self

Set multiple environment variables.

pub fn env_policy(self, policy: EnvPolicy) -> Self

Set the environment policy.

pub fn empty_env(self) -> Self

Start the process with an empty environment.

Trait Implementations

impl Clone for ProcessSpec

fn clone(&self) -> ProcessSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProcessSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ProcessSpec

impl PartialEq for ProcessSpec

fn eq(&self, other: &ProcessSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
