Struct DpMatrix 

pub struct DpMatrix { /* private fields */ }

SIMD-accelerated DP matrix

This matches the C++ SSEMatrix structure with the following layout:

• Elements (cells) are packed into SSE register vectors
• Vectors are packed into quartets (E, F, H, TMP)
• Quartets are packed into columns

The layout is optimized for SIMD operations:

Column 0:     Column 1:     Column 2:
+----+----+  +----+----+  +----+----+
| E0 | H0 |  | E1 | H1 |  | E2 | H2 |
+----+----+  +----+----+  +----+----+
| F0 | TMP|  | F1 | TMP|  | F2 | TMP|
+----+----+  +----+----+  +----+----+

Implementations

impl DpMatrix

pub fn new() -> Self

Create a new DP matrix

pub fn init(&mut self, nrow: usize, ncol: usize, nvecperrow: usize)

Initialize the matrix with the given dimensions

Arguments

• nrow - Number of rows (query characters + 1)
• ncol - Number of columns (reference characters + 1)
• nvecperrow - Number of vectors per row

pub fn is_initialized(&self) -> bool

Check if the matrix is initialized

pub fn clear(&mut self)

Clear the matrix

pub fn ptr(&mut self) -> *mut u8

Get the matrix buffer as a pointer

pub fn as_slice(&self) -> &[u8]

Get the matrix buffer as a slice

pub fn as_mut_slice(&mut self) -> &mut [u8]

Get the matrix buffer as a mutable slice

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

Get a pointer to the E vector at the given row and column

This matches the C++ evec() method.

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

Get a pointer to the F vector at the given row and column

This matches the C++ fvec() method.

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

Get a pointer to the H vector at the given row and column

This matches the C++ hvec() method.

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

Get a pointer to the TMP vector at the given row and column

This matches the C++ tmpvec() method.

pub fn nvecrow(&self) -> usize

Get the number of vector rows

pub fn nveccol(&self) -> usize

Get the number of vector columns

pub fn rowstride(&self) -> usize

Get the row stride in vectors

pub fn colstride(&self) -> usize

Get the column stride in vectors

pub fn size_bytes(&self) -> usize

Get the total size of the matrix in bytes
