Struct storage_api::RawVec

source · [−]

pub struct RawVec<T, S: Storage> { /* private fields */ }

Expand description

A raw vec around some slice storage. Bundles the storage and its handle.

Note that this is even lower level than alloc’s RawVec currently. That raw vec handles amortized growth; this raw vec just does exactly as asked.

Implementations

source

impl<T, S: Storage> RawVec<T, S>

source

pub fn new(storage: S) -> Result<Self, S>

Create a new empty growable slice in the given storage.

source

pub fn as_ref(&self) -> &[MaybeUninit<T>]

Get a reference to the boxed slice.

source

pub fn as_mut(&mut self) -> &mut [MaybeUninit<T>]

Get a mutable reference to the boxed slice.

source

pub fn len(&self) -> usize

Get the length of the slice.

source

pub fn grow_to(&mut self, new_len: usize) -> Result<(), AllocError>

Grow the length of the slice to new_len. Does not change the length if the slice is already long enough. Does not do amortization.

source

pub fn shrink_to(&mut self, new_len: usize) -> Result<(), AllocError>

Shrink the length of the slice to new_len. Does not change the length if the slice is already shorter than the given length.
