Struct Block Transposed Ref &nbsp; Copy item path

impl<'a, T: Copy, const GROUP: usize, const PACK: usize> BlockTransposedRef<'a, T, GROUP, PACK>

pub fn nrows(&self) -> usize

Returns the number of logical rows.

pub fn ncols(&self) -> usize

Returns the number of logical columns (dimensionality).

pub fn padded_ncols(&self) -> usize

Returns the number of physical (padded) columns.

pub const fn group_size(&self) -> usize

Group size (blocking factor GROUP).

pub const fn const_group_size() -> usize

Group size (blocking factor GROUP) as a const function on the type.

pub const fn pack_size(&self) -> usize

Packing factor PACK.

pub fn full_blocks(&self) -> usize

Number of completely full blocks.

pub fn num_blocks(&self) -> usize

Total number of blocks including any partially-filled tail.

pub fn remainder(&self) -> usize

Number of valid elements in the last partially-full block, or 0 if all blocks are full.

pub fn as_ptr(&self) -> *const T

Return a raw typed pointer to the start of the backing data.

pub fn as_slice(&self) -> &'a [T]

Return the backing data as a shared slice.

The returned slice has storage_len() elements — this includes all padding for partial blocks and column-group alignment.

pub unsafe fn block_ptr_unchecked(&self, block: usize) -> *const T

Return a pointer to the start of the given block.

The caller may assume that for the returned pointer ptr, [ptr, ptr + GROUP * padded_ncols) points to valid memory, even for the remainder block.

§Safety

block must be less than self.num_blocks(). No bounds check is performed in release builds; callers must verify the index themselves (e.g. by iterating 0..self.num_blocks()).

pub fn block(&self, block: usize) -> MatrixView<'a, T>

Return a view over a full block as a MatrixView.

The returned view has padded_ncols / PACK rows and GROUP * PACK columns. For PACK == 1 this simplifies to ncols rows and GROUP columns (the standard transposed interpretation).

§Panics

Panics if block >= self.full_blocks().

pub fn remainder_block(&self) -> Option<MatrixView<'a, T>>

Return a view over the remainder block, or None if there is no remainder.

The returned view has the same dimensions as block(): padded_ncols / PACK rows and GROUP * PACK columns.

pub fn get_element(&self, row: usize, col: usize) -> T

Retrieve the value at the logical (row, col).

§Panics

Panics if row >= self.nrows() or col >= self.ncols().

pub fn get_row(&self, i: usize) -> Option<Row<'_, T, GROUP, PACK>>

Get an immutable row view, or None if i is out of bounds.
