pub struct csp_packet_s {
    pub packet_info: csp_packet_s_anon_union,
    pub length: u16,
    pub id: csp_id_t,

CSP Packet.

This structure is constructed to fit with all interface and protocols to prevent the need to copy data (zero copy).

.. note:: In most cases a CSP packet cannot be reused in case of send failure, because the lower layers may add additional data causing increased length (e.g. CRC32), convert the CSP id to different endian (e.g. I2C), etc.

Fields

packet_info: csp_packet_s_anon_union

length: u16

id: csp_id_t

next: *mut csp_packet_s

header: [u8; 8]

Additional header bytes, to prepend packed data before transmission This must be minimum 6 bytes to accomodate CSP 2.0. But some implementations require much more scratch working area for encryption for example.

Ultimately after csp_id_pack() this area will be filled with the CSP header

packet_data_union: csp_packet_s_data_union
