Trait Implementations

impl<F: Clone, S: Clone> Clone for Or<F, S> where
    F: Command,
    S: Command, 

fn clone(&self) -> Or<F, S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F: Command, S: Command> Command for Or<F, S>

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

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>
