Struct LazyLock 

Source 
pub struct LazyLock<T, F = fn() -> T> { /* private fields */ }
Expand description

A synchronization primitive for lazy initialization.

Wraps OnceLock<T> and stores the initialization function in a Mutex<Option<F>>.

Implementations§

Source§

impl<T, F: FnOnce() -> T> LazyLock<T, F>

Source

pub const fn new(f: F) -> Self

Creates a new LazyLock with the given initialization function.

Source

pub fn force(&self) -> &T

Forces initialization and returns a reference to the value.
