pub struct LateStatic<T> { /* private fields */ }

Static value that is manually initialized at runtime.

Implementations

impl<T> LateStatic<T>

pub const fn new() -> Self

Construct a LateStatic.

pub unsafe fn assign(instance: &LateStatic<T>, val: T)

Assign a value to the late static.

This only works once. A second call to assign for a given variable will panic.

Safety

This is completely unsafe if there is even the slightest chance of another thread trying to dereference the variable.

pub unsafe fn clear(instance: &LateStatic<T>)

Invalidate the late static by removing its inner value.

Whether a value is assigned to this LateStatic.

Safety
