Struct MctpI2cEncap

pub struct MctpI2cEncap { /* private fields */ }

Simple packet processing to add/remove the 4 byte MCTP-I2C header.

Implementations

impl MctpI2cEncap

pub fn new(own_addr: u8) -> Self

pub fn own_addr(&self) -> u8

pub fn decode<'f>(&self, packet: &'f [u8], pec: bool) -> Result<(&'f [u8], u8)>

pub fn receive_done_pec<'f>( &self, packet: &[u8], mctp: &'f mut Stack, ) -> Result<Option<(MctpMessage<'f>, u8, ReceiveHandle)>>

Handles a MCTP fragment with the PEC already validated

packet should omit the PEC byte. Returns the MCTP message and the i2c source address.

pub fn send<'f>( &self, i2c_dest: u8, payload: &[u8], out: &'f mut [u8], fragmenter: &mut Fragmenter, ) -> SendOutput<'f>

out must be sized to hold 8+mctp_mtu, to allow for MCTP and I2C headers

TODO: optionally add PEC.

pub fn encode<'f>( &self, i2c_dest: u8, inp: &[u8], out: &'f mut [u8], pec: bool, ) -> Result<&'f mut [u8]>
