macro_rules! s { ($s:expr) => { ... }; () => { ... }; }
Expand description
Converts a str string literal to an owned String.
This macro provides syntactic sugar to convert static str instances to
Strings - this saves having to do "foo".to_owned() or
String::from("foo").
It will also convert any other type that implements the ToString trait
to a String. This is perhaps not as useful as the str conversion, but it
does provide a consistent interface for converting to Strings. When
converting from other types it is likely best to use the standard conversion
functions directly, to avoid confusion, and so the recommendation is to only
use this macro as shorthand for converting str instances.
The inspiration for this macro comes from the velcro
crate, which provides a range of macros for creating collections, building
on the built-in vec! macro.
Examples
use rubedo::s;
assert_eq!(s!("foo"), "foo");
assert_eq!(s!("foo"), "foo".to_owned());
assert_eq!(s!("foo"), "foo".to_string());
assert_eq!(s!("foo"), String::from("foo"));
