Struct pinned_init::InitClosure

pub struct InitClosure<F, T, E>(_, _);

A closure initializer.

Implementations

impl<T, E, F> InitClosure<F, T, E>where
    F: FnOnce(*mut T) -> Result<(), E>,

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 place,
• returns Err(err) iff it encountered an error and then cleaned place, this means:
  • place can be deallocated without UB ocurring,
  • place does not need to be dropped,
  • place is not partially initialized.
• place may move after initialization

unsafe fn __init(self, place: *mut T) -> Result<(), E>

Initializes place.

impl<T, F, E> PinInit<T, E> for InitClosure<F, T, E>where
    F: FnOnce(*mut T) -> Result<(), E>,

unsafe fn __pinned_init(self, place: *mut T) -> Result<(), E>

Initializes place.
