Struct zbus::MessagePrimaryHeader

source ·
pub struct MessagePrimaryHeader { /* private fields */ }
Expand description

The primary message header, which is present in all D-Bus messages.

This header contains all the essential information about a message, regardless of its type.

Implementations§

source§

impl MessagePrimaryHeader

source

pub fn new(msg_type: MessageType, body_len: u32) -> Self

Create a new MessagePrimaryHeader instance.

source

pub fn endian_sig(&self) -> EndianSig

D-Bus code for bytorder encoding of the message.

source

pub fn set_endian_sig(&mut self, sig: EndianSig)

Set the D-Bus code for bytorder encoding of the message.

source

pub fn msg_type(&self) -> MessageType

The message type.

source

pub fn set_msg_type(&mut self, msg_type: MessageType)

Set the message type.

source

pub fn flags(&self) -> BitFlags<MessageFlags>

The message flags.

source

pub fn set_flags(&mut self, flags: BitFlags<MessageFlags>)

Set the message flags.

source

pub fn protocol_version(&self) -> u8

The major version of the protocol the message is compliant to.

Currently only 1 is valid.

source

pub fn set_protocol_version(&mut self, version: u8)

Set the major version of the protocol the message is compliant to.

Currently only 1 is valid.

source

pub fn body_len(&self) -> u32

The byte length of the message body.

source

pub fn set_body_len(&mut self, len: u32)

Set the byte length of the message body.

source

pub fn serial_num(&self) -> Option<&u32>

The serial number of the message (if set).

This is used to match a reply to a method call.

Note: There is no setter provided for this in the public API since this is set by the Connection the message is sent over.
