Struct Arc

#[repr(C)]
pub struct Arc<T: ?Sized + 'static> { /* private fields */ }

Implementations

impl<T> Arc<T>

pub fn new(data: T) -> Self

pub fn into_raw(this: Self) -> *const T

pub fn borrow_arc<'a>(&'a self) -> ArcBorrow<'a, T>

Produce a pointer to the data that can be converted back to an arc

pub fn with_raw_offset_arc<F, U>(&self, f: F) -> U

where F: FnOnce(&RawOffsetArc<T>) -> U,

Temporarily converts |self| into a bonafide RawOffsetArc and exposes it to the provided callback. The refcount is not modified.

pub fn heap_ptr(&self) -> *const c_void

Returns the address on the heap of the Arc itself – not the T within it – for memory reporting.

impl<T: ?Sized> Arc<T>

pub fn ptr_eq(this: &Self, other: &Self) -> bool

impl<T: Clone> Arc<T>

pub fn make_mut(this: &mut Self) -> &mut T

impl<T: ?Sized> Arc<T>

pub fn get_mut(this: &mut Self) -> Option<&mut T>

pub fn is_unique(&self) -> bool

impl<H, T> Arc<HeaderSlice<H, [T]>>

pub fn from_header_and_iter<I>(header: H, items: I) -> Self

where I: Iterator<Item = T> + ExactSizeIterator,

Creates an Arc for a HeaderSlice using the given header struct and iterator to generate the slice. The resulting Arc will be fat.

impl<H: 'static, T: 'static> Arc<HeaderSlice<HeaderWithLength<H>, [T]>>

pub fn into_thin(a: Self) -> ThinArc<H, T>

Converts an Arc into a ThinArc. This consumes the Arc, so the refcount is not modified.

pub fn from_thin(a: ThinArc<H, T>) -> Self

Converts a ThinArc into an Arc. This consumes the ThinArc, so the refcount is not modified.

impl<T: 'static> Arc<T>

pub fn into_raw_offset(a: Self) -> RawOffsetArc<T>

Converts an Arc into a RawOffsetArc. This consumes the Arc, so the refcount is not modified.

pub fn from_raw_offset(a: RawOffsetArc<T>) -> Self

Converts a RawOffsetArc into an Arc. This consumes the RawOffsetArc, so the refcount is not modified.

Trait Implementations

impl<T: ?Sized> AsRef<T> for Arc<T>

impl<T: Default> Default for Arc<T>

fn default() -> Arc<T>

Returns the “default value” for a type.

impl<T: ?Sized> Deref for Arc<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: ?Sized + Display> Display for Arc<T>

Formats the value using the given formatter.

impl<T: ?Sized> Drop for Arc<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T> From<T> for Arc<T>

Converts to this type from the input type.

impl<T: ?Sized + Hash> Hash for Arc<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: ?Sized + Ord> Ord for Arc<T>

fn cmp(&self, other: &Arc<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: ?Sized + PartialEq> PartialEq for Arc<T>

fn eq(&self, other: &Arc<T>) -> bool

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

fn ne(&self, other: &Arc<T>) -> bool

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