Struct pinned_init::PinInitClosure
source · [−]pub struct PinInitClosure<F, T, E>(_, _);Expand description
A closure initializer for pinned data.
Implementations
sourceimpl<T, E, F> PinInitClosure<F, T, E>where
F: FnOnce(*mut T) -> Result<(), E>,
impl<T, E, F> PinInitClosure<F, T, E>where
F: FnOnce(*mut T) -> Result<(), E>,
sourcepub const unsafe fn from_closure(f: F) -> Self
pub const unsafe fn from_closure(f: F) -> Self
Creates a new Init from the given closure
Safety
The closure
- returns
Ok(())iff it initialized every field of slot, - returns
Err(err)iff it encountered an error and then cleaned slot, this means:- slot can be deallocated without UB ocurring,
- slot does not need to be dropped,
- slot is not partially initialized.
