Struct FrameHeader 

pub struct FrameHeader {
    pub msg_length: u16,
    pub crc16: u16,
}

Wraps a complete RPC (Header + data) on stream transports, like a UART.

Fields

msg_length: u16

crc16: u16

Implementations

impl FrameHeader

pub fn new_from_msg(msg: &[u8]) -> Self

Builds a frame header which will wrap the provided msg.

pub fn as_bytes(&self) -> [u8; 4]

Encodes the frame header in its wire format.

pub fn parse<I, E: ParseError<I>>(i: I) -> IResult<I, Self, E>

where I: Input<Item = u8>,

Nom parser which decodes a leading FrameHeader from the input. Can be chained with other nom parsers.

pub fn check_crc<I, E>(&self, data: I) -> Result<(), Err<E>>

where I: Input<Item = u8>,

Checks the CRC matches that computed from the provided payload.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
