Macro init_static 

init_static!() { /* proc-macro */ }

Macro to declare statically stored values with explicit initialization. Similar to lazy_static!, but initialization is not automatic.

Each static declared using this macro:

• Wraps the value type in InitStatic
• Generates an init function that sets the value
• Registers the init function in a distributed slice

The values are initialized when init_static is called.

Example

use init_static::init_static;
use std::error::Error;

init_static! {
    static VALUE: u32 = "42".parse()?;
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    init_static().await?;
    println!("{}", *VALUE);
    Ok(())
}
