Trait cradle::CmdArgument[−][src]

pub trait CmdArgument { }
Expand description

All types that are possible arguments to cmd! have to implement this trait.

Implementations on Foreign Types

Blanket implementation for &_.

Arguments of type &str are passed to the child process as arguments.

Arguments of type String are passed to the child process as arguments.

Allows to use split to split your argument into words:

use cradle::*;

let StdoutTrimmed(output) = cmd!("echo foo".split(' '));
assert_eq!(output, "foo");

Arguments to split must be of type char.

Allows to use split_whitespace to split your argument into words:

use cradle::*;

let StdoutTrimmed(output) = cmd!("echo foo".split_whitespace());
assert_eq!(output, "foo");

Allows to use split_ascii_whitespace to split your argument into words:

use cradle::*;

let StdoutTrimmed(output) = cmd!("echo foo".split_ascii_whitespace());
assert_eq!(output, "foo");

All elements of the given Vec are used as arguments to cmd!. Same as passing in the elements separately.

use cradle::*;

let StdoutTrimmed(output) = cmd!(vec!["echo", "foo"]);
assert_eq!(output, "foo");

Similar to the implementation for Vec<T>. All elements of the array will be used as arguments.

use cradle::*;

let StdoutTrimmed(output) = cmd!(["echo", "foo"]);
assert_eq!(output, "foo");

Only works on rust version 1.51 and up.

Similar to the implementation for Vec<T>. All elements of the slice will be used as arguments.

Arguments of type PathBuf are passed to the child process as arguments.

use cradle::*;
use std::path::PathBuf;

let current_dir: PathBuf = std::env::current_dir().unwrap();
cmd_unit!("ls", current_dir);

Arguments of type &Path are passed to the child process as arguments.

use cradle::*;
use std::path::Path;

let file: &Path = Path::new("./foo");
cmd_unit!("touch", file);
