Expand description

Smart pointer that can initialize memory in-place.

Required Methods§

source

fn try_pin_init<E>(init: impl PinInit<T, E>) -> Result<Pin<Self>, E>
where E: From<AllocError>,

Use the given pin-initializer to pin-initialize a T inside of a new smart pointer of this type.

If T: !Unpin it will not be able to move afterwards.

source

fn try_init<E>(init: impl Init<T, E>) -> Result<Self, E>
where E: From<AllocError>,

Use the given initializer to in-place initialize a T.

Provided Methods§

source

fn pin_init(init: impl PinInit<T>) -> Result<Pin<Self>, AllocError>

Use the given pin-initializer to pin-initialize a T inside of a new smart pointer of this type.

If T: !Unpin it will not be able to move afterwards.

source

fn init(init: impl Init<T>) -> Result<Self, AllocError>

Use the given initializer to in-place initialize a T.

This trait is not object safe.
