Struct sgx_sync::LazyLock

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

A value which is initialized on the first access.

This type is a thread-safe Lazy, and can be used in statics.

Implementations

impl<T, F> LazyLock<T, F>

pub const fn new(f: F) -> LazyLock<T, F>

Creates a new lazy value with the given initializing function.

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

pub fn force(this: &LazyLock<T, F>) -> &T

Forces the evaluation of this lazy value and returns a reference to result. This is equivalent to the Deref impl, but is explicit.

Trait Implementations

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

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

Formats the value using the given formatter.

impl<T: Default> Default for LazyLock<T>

fn default() -> LazyLock<T>

Creates a new lazy value using Default as the initializing function.

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

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.
