Struct EpHeader 

pub struct EpHeader {
    pub pdu_type: PduType,
    pub user_flag: bool,
    pub service_group: u8,
    pub procedure_id: u8,
}

Parsed SDLS-EP PDU header.

Wire format (3 bytes, per Figure 5-2): byte 0 (Tag): type(1) | user_flag(1) | service_group(2) | procedure_id(4) byte 1-2: data field length in bits (16-bit BE, octet-aligned)

Fields

pdu_type: PduType

Command or reply.

user_flag: bool

User-defined extension flag.

service_group: u8

Service group (2 bits).

procedure_id: u8

Procedure identifier within the service group (4 bits).

Implementations

impl EpHeader

pub fn parse(bytes: &[u8]) -> Result<(Self, u16), Error>

Parse an EP header from a byte buffer.

Returns the header and the data field length in bytes.

pub fn encode( &self, data_len_bytes: u16, out: &mut [u8], ) -> Result<usize, Error>

Encode the EP header into a buffer.

data_len_bytes is the data field length in bytes; it is encoded as bits in the wire format.
