Classes
struct	mm::node::ProcessBuffer
	Fixed-capacity byte buffer for one direction of the process image. More...
struct	mm::node::ProcessImageEntry
	Locates one mapped object within the flat process image. More...
struct	mm::node::ProcessImage
	The whole bus's process-data layout, resolved to absolute positions. More...
struct	mm::node::ProcessImage::Location
	Where a mapped object sits in the image, and which direction it belongs to. More...

Functions
std::vector< uint8_t >	mm::node::extractBits (std::span< const uint8_t > src, uint32_t bitOffset, uint16_t bitLength)
	Extracts bitLength bits at bitOffset from src into a fresh LSB-aligned little-endian byte vector (ceil(bitLength/8) bytes), as the SDO encoding would.
void	mm::node::insertBits (std::span< uint8_t > dst, uint32_t bitOffset, uint16_t bitLength, std::span< const uint8_t > value)
	Inserts bitLength bits of value (LSB-first) into dst at bitOffset.
std::expected< ProcessImage, std::string >	mm::node::buildProcessImage (const mm::comm::PdoLayout &layout, const std::vector< Device > &devices)
	Assembles a ProcessImage from the driver layout and per-device PDO mappings.
