Struct ThreadUnsafeOnceCellDropStrategy 

pub struct ThreadUnsafeOnceCellDropStrategy<M: Mode> {
    pub inner: Rc<OnceCell<Error>>,
    /* private fields */
}

A drop strategy which sets an error value once.

For more information see it’s thread safe counterpart.

Fields

inner: Rc<OnceCell<Error>>

The inner error value.

Implementations

impl ThreadUnsafeOnceCellDropStrategy<Ignore>

pub fn ignore(value: Rc<OnceCell<Error>>) -> Self

Create a new once cell drop strategy which will ignore if there is already an error value in its cell.

impl ThreadUnsafeOnceCellDropStrategy<Error>

pub fn error(value: Rc<OnceCell<Error>>) -> Self

Create a new once cell drop strategy which will error if there is already an error value in its cell.

impl<M: Mode> ThreadUnsafeOnceCellDropStrategy<M>

pub fn new(value: Rc<OnceCell<Error>>) -> Self

Create a new once cell drop strategy which sets an error value once.
