Function quote 

pub fn quote(value: &str) -> String

Quote a value for safe shell usage

The value is always treated as literal text - exactly one argument, spaces and quote characters included - which is what "$var" does in sh.

Examples

use command_stream::quote::quote;

// Safe characters are passed through unchanged
assert_eq!(quote("hello"), "hello");
assert_eq!(quote("/path/to/file"), "/path/to/file");

// Special characters are quoted
assert_eq!(quote("hello world"), "'hello world'");

// Paths with spaces stay a single argument
assert_eq!(quote("/My Documents/report.txt"), "'/My Documents/report.txt'");

// Single quotes in strings are escaped
assert_eq!(quote("it's"), "'it'\\''s'");

// Empty strings are quoted
assert_eq!(quote(""), "''");
