Struct nalgebra::base::default_allocator::DefaultAllocator

pub struct DefaultAllocator;

An allocator based on ArrayStorage and [VecStorage] for statically-sized and dynamically-sized matrices respectively.

Trait Implementations

impl<T: Scalar, const R: usize, const C: usize> Allocator<T, Const<R>, Const<C>> for DefaultAllocator

type Buffer = ArrayStorage<T, R, C>

The type of buffer this allocator can instantiate.

type BufferUninit = ArrayStorage<MaybeUninit<T>, R, C>

The type of buffer with uninitialized components this allocator can instantiate.

fn allocate_uninit( _: Const<R>, _: Const<C>, ) -> ArrayStorage<MaybeUninit<T>, R, C>

Allocates a buffer with the given number of rows and columns without initializing its content.

unsafe fn assume_init( uninit: ArrayStorage<MaybeUninit<T>, R, C>, ) -> ArrayStorage<T, R, C>

Assumes a data buffer to be initialized.

fn allocate_from_iterator<I: IntoIterator<Item = T>>( nrows: Const<R>, ncols: Const<C>, iter: I, ) -> Self::Buffer

Allocates a buffer initialized with the content of the given iterator.

fn allocate_from_row_iterator<I: IntoIterator<Item = T>>( nrows: R, ncols: C, iter: I, ) -> Self::Buffer

Allocates a buffer initialized with the content of the given row-major order iterator.

impl Clone for DefaultAllocator

fn clone(&self) -> DefaultAllocator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DefaultAllocator

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

Formats the value using the given formatter.

impl<T: Scalar, RFrom, CFrom, const RTO: usize, const CTO: usize> Reallocator<T, RFrom, CFrom, Const<RTO>, Const<CTO>> for DefaultAllocator

where RFrom: Dim, CFrom: Dim, Self: Allocator<T, RFrom, CFrom>,

unsafe fn reallocate_copy( rto: Const<RTO>, cto: Const<CTO>, buf: <Self as Allocator<T, RFrom, CFrom>>::Buffer, ) -> ArrayStorage<MaybeUninit<T>, RTO, CTO>

Reallocates a buffer of shape (RTo, CTo), possibly reusing a previously allocated buffer buf. Data stored by buf are linearly copied to the output:
