Struct DataSquare 

pub struct DataSquare {
    pub square_row: Matrix3D,
    pub square_col: Matrix3D,
    pub width: usize,
    pub original_width: usize,
    pub chunk_size: usize,
    pub row_roots: Matrix2D,
    pub col_roots: Matrix2D,
    pub codec: Box<dyn Codec>,
}

Store all data for an original data square (ODS) or extended data square (EDS). Data is duplicated in both row-major and column-major order in order to be able to provide zero-allocation column slices.

Fields

square_row: Matrix3D

square_col: Matrix3D

width: usize

original_width: usize

chunk_size: usize

row_roots: Matrix2D

col_roots: Matrix2D

codec: Box<dyn Codec>

Implementations

impl DataSquare

pub fn new(original_data: Matrix2D) -> Result<Self>

Create a new data square. Data must be a square matrix. Data must not be empty.

Arguments

• original_data - Original data.
• merkle_tree - MerkleTree.

Returns

• DataSquare - Data square.
• Result - Error.

pub fn erasure_extend_square(&mut self) -> Result<()>

Extend original square horizontally and vertically
