Struct Single

pub struct Single(/* private fields */);

Holds a single command to be run.

Implementations

impl Single

pub fn new(command: &str) -> Self

Creates a new Command which can be run in the shell.

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

where S: AsRef<str>,

Adds an argument to the command.

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

where I: IntoIterator<Item = S>, S: AsRef<str>,

Adds multiple arguments.

Trait Implementations

impl Clone for Single

fn clone(&self) -> Single

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Command for Single

fn run_internal( &self, input: Option<&str>, do_clear_env: bool, env: HashMap<String, String>, del_env: HashSet<String>, path: Option<PathBuf>, ) -> Result<Output, Error>

The command used to define all others. input: the string to be piped into the next command run. clear_env: if the global enviromental variables should be cleared. env: what enviromental variables to set, supercedes clear_env.

fn and<C: Command>(self, other: C) -> And<Self, C>

Equivalent to &&, as in “command 1” && “command 2”.

fn or<C: Command>(self, other: C) -> Or<Self, C>

Equivalent to ||, as in “command 1” || “command 2”.

fn then<C: Command>(self, other: C) -> Then<Self, C>

Equivalent to ;, as in “command 1”; “command 2”.

fn pipe<C: Command>(self, other: C) -> Pipe<Self, C>

Equivalent to |, as in “pipe 1” | “into 2”.

fn env(self, key: &str, value: &str) -> Env<Self>

Sets the env in the environment the command is run in.

fn clear_envs(self) -> ClearEnv<Self>

Clears the environment for non-explicitly set variables.

fn without_env(self, key: &str) -> ExceptEnv<Self>

Removes a variable from the enviroment in which the command is run.

fn without_envs<I: IntoIterator<Item = String>>( self, envs: I, ) -> ExceptEnvs<Self, I>

Takes an iterable of Strings for keys to remove.

fn with_dir<P: AsRef<Path>>(self, dir: P) -> Dir<Self>

fn run(&self) -> Result<Output>

Runs the command.

fn with_input(self, input: &str) -> Input<Self>

Pipes input into the following command.

impl Debug for Single

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

Formats the value using the given formatter.

impl PartialEq for Single

fn eq(&self, other: &Single) -> 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.
