Struct InternedSliceRef 

#[repr(transparent)]
pub struct InternedSliceRef<'a, T> {
    ptr: NonNull<c_void>,
    _marker: PhantomData<&'a T>,
}

Fields

ptr: NonNull<c_void>

Invariant

There is no ThinArcBorrow unfortunately, so this is basically a ManuallyDrop<ThinArc>, except that can’t be Copy, so we store a raw pointer instead.

_marker: PhantomData<&'a T>

Implementations

impl<'a, T: SliceInternable> InternedSliceRef<'a, T>

fn arc(self) -> ManuallyDrop<ThinArc<T::Header, T::SliceType>>

pub fn to_owned(self) -> InternedSlice<T>

pub fn get( self, ) -> &'a HeaderSlice<HeaderWithLength<<T as SliceInternable>::Header>, [<T as SliceInternable>::SliceType]>

pub unsafe fn decrement_refcount(self)

Safety

You have to make sure the data is not referenced after the refcount reaches zero; beware the interning map also keeps a reference to the value.

pub(crate) fn strong_count(self) -> usize

pub(crate) fn as_raw(self) -> *const c_void

pub fn change_lifetime<'b>(self) -> InternedSliceRef<'b, T>

Available only on GC mode.

Changes the attached lifetime, as in GC mode, the lifetime is more kind of a lint to prevent misuse than actual soundness check.

Trait Implementations

impl<T> Clone for InternedSliceRef<'_, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for InternedSliceRef<'_, T>

where T: SliceInternable, T::SliceType: Debug, T::Header: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: SliceInternable> Deref for InternedSliceRef<'_, T>

type Target = HeaderSlice<HeaderWithLength<<T as SliceInternable>::Header>, [<T as SliceInternable>::SliceType]>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: SliceInternable> Hash for InternedSliceRef<'_, T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: SliceInternable> PartialEq for InternedSliceRef<'_, T>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
