Function get

pub fn get<T: Send + Sync + 'static>() -> Result<Arc<T>, String>

Retrieves a value of type T from the global registry.

Returns

• Ok(Arc<T>) if the type is found and the downcast is successful
• Err(String) in the following cases:
  • Failed to acquire the registry lock
  • Type T is not found in the registry
  • Type mismatch (found a different type with the same TypeId)

Examples

use singleton_registry::{register, get};
use std::sync::Arc;

// Register and retrieve a value
register(42i32);
let num: Arc<i32> = get().expect("Failed to get i32");
assert_eq!(*num, 42);

// Handle missing value
let result: Result<Arc<String>, _> = get();
assert!(result.is_err());
