Struct MessageHeader

pub struct MessageHeader { /* private fields */ }

This represents a DBus message header.

Implementations

impl Header

pub fn new( is_le: bool, message_type: MessageType, message_flags: MessageFlags, version: u8, serial: u32, fields: HeaderFields, ) -> Result<Header, HeaderError>

Create a [MessageHeader] object. It can fail if the required header fields are not present.

pub const fn get_serial(&self) -> u32

Get the serial number.

pub const fn get_path(&self) -> Option<&ObjectPath>

Get the path, if there is one in the header field.

pub const fn has_path(&self) -> bool

It is true if the message contains a path in the header fields.

pub const fn get_interface(&self) -> Option<&Interface>

Get the interface, if there is one in the header field.

pub const fn has_interface(&self) -> bool

It is true if the message contains an interface in the header fields.

pub const fn get_member(&self) -> Option<&Member>

Get the member, if there is one in the header field.

pub const fn has_member(&self) -> bool

It is true if the message contains a member in the header fields.

pub const fn get_error_name(&self) -> Option<&Error>

Get the error_name, if there is one in the header field.

pub const fn has_error_name(&self) -> bool

It is true if the message contains an error_name in the header fields.

pub const fn get_destination(&self) -> Option<&Bus>

Get the destination, if there is one in the header field.

pub const fn has_destination(&self) -> bool

It is true if the message contains a destination in the header fields.

pub const fn get_sender(&self) -> Option<&Bus>

Get the sender, if there is one in the header field.

pub const fn has_sender(&self) -> bool

It is true if the message contains a sender in the header fields.

pub const fn get_reply_serial(&self) -> Option<u32>

Get the reply_serial, if there is one in the header field.

pub const fn has_reply_serial(&self) -> bool

It is true if the message contains a reply_serial in the header fields.

pub fn get_signature(&self) -> Option<&[Type]>

Get the signature, if there is one in the header field.

pub const fn has_signature(&self) -> bool

It is true if the message contains a signature in the header fields.

pub const fn get_unix_fds(&self) -> Option<u32>

Get the unix_fds, if there is one in the header field.

pub const fn has_unix_fds(&self) -> bool

It is true if the message contains a unix_fds in the header fields.

pub fn method_return(&self) -> Result<Message, Message>

Create a message return from this Message. Only works if this Message is a MethodCall.

pub fn unknown_property(&self, property: &str) -> Message

Create a unknown property error message from this Message.

pub fn unknown_path(&self) -> Option<Message>

Create a unknown path error message from this Message.

pub fn unknown_interface(&self) -> Option<Message>

Create a unknown interface error message from this Message.

pub fn unknown_member(&self) -> Option<Message>

Create a unknown member error message from this Message.

pub fn invalid_args(&self, reason: String) -> Message

Create an invalid args error message from this Message.

pub fn error(&self, error: Error, message: String) -> Message

Create an error message from this Message.

pub fn get_type(&self) -> MessageType

Get the message type.

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 Ord for Header

fn cmp(&self, other: &Header) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for Header

fn partial_cmp(&self, other: &Header) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
