Struct toolshed::Uninitialized
source · pub struct Uninitialized<'arena, T: 'arena> { /* private fields */ }Expand description
A pointer to an uninitialized region of memory.
Implementations
sourceimpl<'arena, T: 'arena> Uninitialized<'arena, T>
impl<'arena, T: 'arena> Uninitialized<'arena, T>
sourcepub fn init(self, value: T) -> &'arena mut T
pub fn init(self, value: T) -> &'arena mut T
Initialize the memory at the pointer with a given value.
sourcepub unsafe fn as_ref(&self) -> &'arena T
pub unsafe fn as_ref(&self) -> &'arena T
Get a reference to the pointer without writing to it.
Reading from this reference without calling init is undefined behavior.
sourcepub unsafe fn as_mut_ref(self) -> &'arena mut T
pub unsafe fn as_mut_ref(self) -> &'arena mut T
Convert the Uninitialized to a regular mutable reference.
Reading from this reference without calling init is undefined behavior.
