File formats

There are two different file formats used to store program output. repr mode generates files with the extension .mm-repr and dist mode generates files with the extension .mm-dist.

Data is always stored in little-endian format. All header values except the signature are unsigned integers.

element_type is a common enum used to specify the type of the stored data. Its values are as follows:

repr format (.mm-repr files)

Header

If the sparse flag is not set, the following count * rows * columns * (size for value_type) bytes are the entries, in row-major order, for each of the count matrices, one after the other.

If the sparse flag is set, each of the count matrices, one after the other, is stored as (the matrix size from sizes) * (size for key_type) * (size for value_type) bytes which are (the matrix size from sizes) pairs of key followed by value. The order of keys is unspecified.

dist format (.mm-dist files)

Header

The following (size * (size - 1)) / 2 * (size for value_type) bytes are the entries above the main diagonal, in row-major order, of the matrix. The matrix is assumed to be symmetric and have zeros on the main diagonal.
