Macro module_id::ident_str

macro_rules! ident_str {
    ($ident:expr) => { ... };
}

ident_str! is a compile-time validated macro that constructs a &'static IdentStr from a const &'static str.

Example

Creating a valid static or const IdentStr:

use move_core_types::{ident_str, identifier::IdentStr};
const VALID_IDENT: &'static IdentStr = ident_str!("MyCoolIdentifier");

const THING_NAME: &'static str = "thing_name";
const THING_IDENT: &'static IdentStr = ident_str!(THING_NAME);

In contrast, creating an invalid IdentStr will fail at compile time:

use move_core_types::{ident_str, identifier::IdentStr};
const INVALID_IDENT: &'static IdentStr = ident_str!("123Foo"); // Fails to compile!
