Macro dipstick::labels

macro_rules! labels {
    (@single $($x:tt)*) => { ... };
    (@count $($rest:expr),*) => { ... };
    ($($key:expr => $value:expr,)+) => { ... };
    ($($key:expr => $value:expr),*) => { ... };

Create Labels from a list of key-value pairs Adapted from the hashmap!() macro in the maplit crate.

Example

#[macro_use] ///
use dipstick::*;


let labels = labels!{

    "a" => "1",
    "b" => "2",
};
assert_eq!(labels.lookup("a"), Some(::std::sync::Arc::new("1".into())));
assert_eq!(labels.lookup("b"), Some(::std::sync::Arc::new("2".into())));
assert_eq!(labels.lookup("c"), None);
