Macro item_hash 

macro_rules! item_hash {
    ($hash:expr) => { ... };
}

Macro for creating ItemHash instances from hex string literals.

This macro simplifies creating ItemHash instances in tests and other code by panicking on invalid input (similar to vec! or format!).

Example

use aleph_types::item_hash;
let hash = item_hash!("3c5b05761c8f94a7b8fe6d0d43e5fb91f9689c53c078a870e5e300c7da8a1878");
