Struct EncapsulationHeader 

pub struct EncapsulationHeader {
    pub command: u16,
    pub length: u16,
    pub session_handle: u32,
    pub status: u32,
    pub sender_context: [u8; 8],
    pub options: u32,
}

The fixed 24-byte EtherNet/IP encapsulation header.

Fields

command: u16

Encapsulation command code.

length: u16

Payload length following the header.

session_handle: u32

Session handle assigned by the target.

status: u32

Encapsulation status code.

sender_context: [u8; 8]

Caller-controlled correlation bytes echoed by the target.

options: u32

Encapsulation options; currently required to be zero.

Implementations

impl EncapsulationHeader

pub fn new(command: u16, length: u16, session_handle: u32) -> Self

Creates a header with zero status, context, and options.

pub fn send_rr_data(length: u16, session_handle: u32) -> Self

Creates a SendRRData header with the library’s default sender context.

pub fn send_rr_data_with_context( length: u16, session_handle: u32, sender_context: [u8; 8], ) -> Self

Creates a SendRRData header with an explicit correlation context.
