Struct ThinVecWithHeader

pub struct ThinVecWithHeader<Header, Item> { /* private fields */ }

A type that is functionally equivalent to (Header, Box<[Item]>), but all data is stored in one heap allocation and the pointer is thin, so the whole thing’s size is like a pointer.

Implementations

impl<Header, Item> ThinVecWithHeader<Header, Item>

pub fn from_iter<I>(header: Header, items: I) -> Self

where I: IntoIterator, I::IntoIter: TrustedLen<Item = Item>,

pub fn header(&self) -> &Header

pub fn header_mut(&mut self) -> &mut Header

pub fn items(&self) -> &[Item]

pub fn items_mut(&mut self) -> &mut [Item]

pub fn len(&self) -> usize

Trait Implementations

impl<Header: Clone, Item: Clone> Clone for ThinVecWithHeader<Header, Item>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Header: Debug, Item: Debug> Debug for ThinVecWithHeader<Header, Item>

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

Formats the value using the given formatter.

impl<Header, Item> Drop for ThinVecWithHeader<Header, Item>

fn drop(&mut self)

Executes the destructor for this type.

impl<Header: Hash, Item: Hash> Hash for ThinVecWithHeader<Header, Item>

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<Header: PartialEq, Item: PartialEq> PartialEq for ThinVecWithHeader<Header, Item>

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.
