Struct Header 

pub struct Header {
    pub message_id: MessageId,
    pub length: u32,
    pub request_id: u32,
    pub protocol_version: u8,
    pub interface_version: u8,
    pub message_type: MessageTypeField,
    pub return_code: ReturnCode,
}

SOME/IP header

Fields

message_id: MessageId

Message ID, encoding service ID and method ID

length: u32

Length of the message in bytes, starting at the request Id Total length of the message is therefore length + 8

request_id: u32

SOME/IP Request ID (4 bytes): Client ID [31:16] + Session ID [15:0].

protocol_version: u8

interface_version: u8

message_type: MessageTypeField

return_code: ReturnCode

Implementations

impl Header

pub fn upper_header_bytes(&self) -> [u8; 8]

Return the 8-byte “upper header” used by E2E UPPER-HEADER-BITS-TO-SHIFT.

Layout (big-endian): request_id(4) + protocol_version(1) + interface_version(1) + message_type(1) + return_code(1)

Note: request_id is the full 4-byte SOME/IP Request ID field (Client ID [31:16] + Session ID [15:0]), not just the 2-byte Session ID.

pub fn new_sd(request_id: u32, sd_header_size: usize) -> Self

pub const fn is_sd(&self) -> bool

pub const fn payload_size(&self) -> usize

pub fn set_request_id(&mut self, request_id: u32)

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Header

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Header

fn eq(&self, other: &Header) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl WireFormat for Header

fn decode<T: Read>(reader: &mut T) -> Result<Self, Error>

Deserialize a value from a byte stream. Returns Ok(Some(value)) if the stream contains a complete value. Returns Ok(None) if the stream is empty.

fn required_size(&self) -> usize

Returns the number of bytes required to serialize this value.

fn encode<T: Write>(&self, writer: &mut T) -> Result<usize, Error>

Serialize a value to a byte stream. Returns the number of bytes written.

impl Eq for Header

impl StructuralPartialEq for Header
