struct TypedArray

Public Functions

inline bool empty() const

inline size_t size() const

template<typename T>
inline Eigen::Map<Eigen::Matrix<T, Eigen::Dynamic, Eigen::Dynamic, Eigen::RowMajor>> as_matrix()

View the buffer as a row-major Eigen matrix of type T.

This is a zero-copy view over the underlying memory map. The dtype must match the requested T or an exception is thrown.

template<typename T>
inline Eigen::Map<const Eigen::Matrix<T, Eigen::Dynamic, Eigen::Dynamic, Eigen::RowMajor>> as_matrix() const

View the buffer as a const row-major Eigen matrix of type T.

This is a zero-copy view over the underlying memory map. The dtype must match the requested T or an exception is thrown.

inline ByteView to_bytes() const

Return a read-only byte view of the underlying buffer.

The size is computed from dtype * rows * cols. This is useful for interop, hashing, or serialization without exposing raw pointers.

inline MutableByteView to_bytes_mutable()

Return a mutable byte view of the underlying buffer.

The size is computed from dtype * rows * cols. Use with care: mutating the bytes will mutate the mapped file contents.
