Struct Command

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

Abstraction of an external command.

Example

let cmd = Command::parse_str(r#"grep -Eo "\w\w\sa[^.]*""#)?;

// or

let cmd = Command::new("grep").args(&["-Eo", r"\w\w\sa[^.]*"]);

Implementations

impl Command

pub fn new<S>(command: S) -> Self

where S: AsRef<OsStr>,

Creates a new command instance.

Example

let cmd = Command::new("ls");

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

where S: AsRef<OsStr>,

Adds a single argument to an existing Command instance.

Example

let cmd = Command::new("ls").arg("-la");

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

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

Adds a multiple arguments to an existing Command instance.

Example

let cmd = Command::new("grep").args(&["-Eo", r"\w\w\sa[^.]*"]);

pub fn parse_str(c: &str) -> Result<Self, APipeError>

Constructs a Command from a string including the program and its args.

Example

    let cmd = Command::parse_str(r#"grep -Eo "\w\w\sa[^.]*""#)?;
