LazyLock

This class provides a mechanism for lazy initialization of a value, ensuring that the initialization function is only invoked once upon the first access. It utilizes a synchronization primitive to manage the internal state, making it suitable for scenarios where a value is expensive to compute and may not always be needed.

Attributes

Attribute	Type	Description
init	fn()- > T	A function pointer used to initialize the value on the first access.
value	OnceLock< T >	A synchronization primitive that stores the initialized data and ensures it is only computed once.

Constructor

Signature

def LazyLock(
    init: fn()- > T,
    value: OnceLock< T >
) - > [LazyLock](lazylock.md?sid=build_tools_lazylock)

Parameters

Name	Type	Description
init	fn()- > T	A function that produces the value when called.
value	OnceLock< T >	The synchronization primitive used to store the initialized value.

---

Signature

@classmethod
def new(
    init: fn()- > T
) - > LazyLock< T >

Parameters

Name	Type	Description
init	fn()- > T	The function or closure used to compute the value when it is first requested.

---

Methods

---

force()

def force() - > &T

Ensures the value is initialized and returns a reference to it, triggering the initialization function if it has not been called yet.

Returns

Type	Description
&T	A reference to the initialized value.
