Implementations

source

impl<'a, T, R> SelfReference<'a, T, R>where
for<'this> R: RefDef<'this>,
for<'this> <R as RefDef<'this>>::Type: 'a,

source

pub fn new<F>(object: T, init: F) -> Selfwhere
F: FnOnce() -> <R as RefDef<'static>>::Type,

You will “never” able to hold object before its pinned. try initializing as empty static object. (using Option, NonNull or Empty enum field)

source

pub fn new_stable<F>(object: T, init: F) -> Selfwhere
T: StableDeref + DerefMut,
F: FnOnce(&mut T::Target) -> <R as RefDef<'_>>::Type,

source

pub fn reset<'s, F>(self: Pin<&'s mut Self>, f: F)where
F: FnOnce(Pin<&'s mut T>) -> <R as RefDef<'s>>::Type,

reset referenceial object using object. object is now pinned so initializing referential type is safe. This is also useful when you consumed your own reference. (like in AsyncIterator)

source

pub fn pin_mut<'s>(
self: Pin<&'s mut Self>
) -> Pin<&'s mut <R as RefDef<'s>>::Type>

get pinned mutable referencial object that has self lifetime.

source

pub fn pin_ref<'s>(self: Pin<&'s Self>) -> Pin<&'s <R as RefDef<'s>>::Type>

get pinned referencial object that has self lifetime.

source

impl<'a, T, R> SelfReference<'a, T, R>where
 for<'this> R: RefDef<'this>,
 for<'this> <R as RefDef<'this>>::Type: 'a,
 for<'this> <R as RefDef<'this>>::Type: Unpin,

source

pub fn get_mut<'s>(self: Pin<&'s mut Self>) -> &'s mut <R as RefDef<'s>>::Type

get mutable referencial object that has self lifetime.

source

pub fn get_ref<'s>(self: Pin<&'s Self>) -> &'s <R as RefDef<'s>>::Type

get referencial object that has self lifetime.

source

impl<'a, T, R> SelfReference<'a, T, R>where
 for<'this> R: RefDef<'this>,
 for<'this> <R as RefDef<'this>>::Type: 'a,
 T: Unpin,

source

pub fn reset_unpin<'s, F>(self: Pin<&'s mut Self>, f: F)where
F: FnOnce(&'s mut T) -> <R as RefDef<'s>>::Type,

reset referenceial object using unpinned object. object is now pinned so initializing referential type is safe. This is also useful when you consumed your own reference. (like in AsyncIterator)
