Struct ThinBox

pub struct ThinBox<Head, SliceItem> { /* private fields */ }

A thin version of Box.

Implementations

impl<Head, SliceItem> ThinBox<Head, SliceItem>

pub unsafe fn from_erased(ptr: ErasedPtr) -> Self

Construct an owned pointer from an erased pointer.

Safety

This pointer must logically own a valid instance of Self.

pub fn erase(this: Self) -> ErasedPtr

Convert this owned pointer into an erased pointer.

To avoid a memory leak the pointer must be converted back using Self::from_erased.

impl<Head, SliceItem> ThinBox<Head, SliceItem>

pub fn new<I>(head: Head, slice: I) -> Self

where I: IntoIterator<Item = SliceItem>, I::IntoIter: ExactSizeIterator,

Create a new boxed ThinData with the given head and slice.

Panics

Panics if the slice iterator incorrectly reports its length.

Trait Implementations

impl<Head, SliceItem> Clone for ThinBox<Head, SliceItem>

where Head: Clone, SliceItem: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

type Target = ThinData<Head, SliceItem>

The resulting type after dereferencing.

fn deref(&self) -> &ThinData<Head, SliceItem>

Dereferences the value.

impl<Head, SliceItem> DerefMut for ThinBox<Head, SliceItem>

Converts to this type from the input type.

impl<Head, SliceItem> From<ThinBox<Head, SliceItem>> for Box<ThinData<Head, SliceItem>>

fn from(this: ThinBox<Head, SliceItem>) -> Self

Converts to this type from the input type.

impl<Head, SliceItem> Hash for ThinBox<Head, SliceItem>

where Box<ThinData<Head, SliceItem>>: Hash,

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

where H: Hasher,

Feeds this value into the given Hasher.

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

impl<Head, SliceItem> PartialEq<Box<ThinData<Head, SliceItem>>> for ThinBox<Head, SliceItem>

where Box<ThinData<Head, SliceItem>>: PartialEq,

fn eq(&self, other: &Box<ThinData<Head, SliceItem>>) -> 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.
