Struct static_init::ThreadLocalLazy

pub struct ThreadLocalLazy<T, F = fn() -> T> { /* private fields */ }

The type of thread local lazy.

Implementations

impl<T, F> Lazy<T, F>

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

Initialize a lazy with a builder as argument.

pub const fn as_mut_ptr(this: &Self) -> *mut T

Return a pointer to the value.

The value may be in an uninitialized state.

pub fn __do_init(this: &Self)where
    F: FnOnce() -> T,

Ensure the value is initialized

Once this function is called, it is guaranteed that the value is in an initialized state.

This function is always called when the lazy is dereferenced.

pub fn ensure_init(this: &Self)where
    F: FnOnce() -> T,

Ensure the value is initialized

Once this function is called, it is guaranteed that the value is in an initialized state.

This function is always called when the lazy is dereferenced.

pub unsafe fn drop(this: &Self)

Drop the contained value

Safety

The value should not be accessed any more.

Trait Implementations

impl<T: Debug, F> Debug for Lazy<T, F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T, F> Deref for Lazy<T, F>where
    F: FnOnce() -> T,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T, F> DerefMut for Lazy<T, F>where
    F: FnOnce() -> T,

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.
