• 'a: The lifetime of the computation
• D: The type of the deferred value.
• F: The type of the thunk.

• f: A thunk that produces the value.

Returns

The deferred value.

use fp_library::{brands::*, functions::*, types::*};

let eval: Thunk<i32> = defer(|| Thunk::new(|| 42));
assert_eq!(eval.evaluate(), 42);
