Expand description

A matrix allocator of a memory buffer that may contain R::to_usize() * C::to_usize() elements of type T.

An allocator is said to be: − static: if R and C both implement DimName. − dynamic: if either one (or both) of R or C is equal to Dyn.

Every allocator must be both static and dynamic. Though not all implementations may share the same Buffer type.

Required Associated Types§

source

type Buffer: StorageMut<T, R, C> + IsContiguous + Clone + Debug

The type of buffer this allocator can instantiate.

source

type BufferUninit: RawStorageMut<MaybeUninit<T>, R, C> + IsContiguous

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

Required Methods§

source

fn allocate_uninit(nrows: R, ncols: C) -> Self::BufferUninit

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

source

unsafe fn assume_init(uninit: Self::BufferUninit) -> Self::Buffer

Assumes a data buffer to be initialized.

§Safety

The user must make sure that every single entry of the buffer has been initialized, or Undefined Behavior will immediately occur.

source

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

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

Provided Methods§

source

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

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

Object Safety§

This trait is not object safe.
