Enum zbus::MessageFlags

#[repr(u8)]
pub enum MessageFlags {
    NoReplyExpected = 1,
    NoAutoStart = 2,
    AllowInteractiveAuth = 4,
}

Pre-defined flags that can be passed in Message header.

Variants

NoReplyExpected = 1

This message does not expect method return replies or error replies, even if it is of a type that can have a reply; the reply should be omitted.

Note that MessageType::MethodCall is the only message type currently defined in the specification that can expect a reply, so the presence or absence of this flag in the other three message types that are currently documented is meaningless: replies to those message types should not be sent, whether this flag is present or not.

NoAutoStart = 2

The bus must not launch an owner for the destination name in response to this message.

AllowInteractiveAuth = 4

This flag may be set on a method call message to inform the receiving side that the caller is prepared to wait for interactive authorization, which might take a considerable time to complete. For instance, if this flag is set, it would be appropriate to query the user for passwords or confirmation via Polkit or a similar framework.

Trait Implementations

impl BitAnd for MessageFlags

type Output = BitFlags<MessageFlags>

The resulting type after applying the & operator.

fn bitand(self, other: Self) -> Self::Output

Performs the & operation.

impl BitFlag for MessageFlags

fn empty() -> BitFlags<Self>

Create a BitFlags with no flags set (in other words, with a value of 0).

fn all() -> BitFlags<Self>

Create a BitFlags with all flags set.

fn from_bits(bits: Self::Numeric) -> Result<BitFlags<Self>, FromBitsError<Self>>

Create a BitFlags if the raw value provided does not contain any illegal flags.

fn from_bits_truncate(bits: Self::Numeric) -> BitFlags<Self>

Create a BitFlags from an underlying bitwise value. If any invalid bits are set, ignore them.

unsafe fn from_bits_unchecked(bits: Self::Numeric) -> BitFlags<Self>

Create a BitFlags unsafely, without checking if the bits form a valid bit pattern for the type.

impl BitOr for MessageFlags

type Output = BitFlags<MessageFlags>

The resulting type after applying the | operator.

fn bitor(self, other: Self) -> Self::Output

Performs the | operation.

impl BitXor for MessageFlags

type Output = BitFlags<MessageFlags>

The resulting type after applying the ^ operator.

fn bitxor(self, other: Self) -> Self::Output

Performs the ^ operation.

impl Clone for MessageFlags

fn clone(&self) -> MessageFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MessageFlags

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

Formats the value using the given formatter.

impl From<MethodFlags> for MessageFlags

fn from(method_flag: MethodFlags) -> Self

Converts to this type from the input type.

impl Not for MessageFlags

type Output = BitFlags<MessageFlags>

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for MessageFlags

fn eq(&self, other: &MessageFlags) -> 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 RawBitFlags for MessageFlags

type Numeric = u8

The underlying integer type.

const EMPTY: Self::Numeric = {transmute(0x00): <message_header::MessageFlags as enumflags2::_internal::RawBitFlags>::Numeric}

A value with no bits set.

const DEFAULT: Self::Numeric = {transmute(0x00): <message_header::MessageFlags as enumflags2::_internal::RawBitFlags>::Numeric}

The value used by the Default implementation. Equivalent to EMPTY, unless customized.

const ALL_BITS: Self::Numeric = {transmute(0x07): <message_header::MessageFlags as enumflags2::_internal::RawBitFlags>::Numeric}

A value with all flag bits set.

const BITFLAGS_TYPE_NAME: &'static str = "BitFlags<MessageFlags>"

The name of the type for debug formatting purposes.

fn bits(self) -> Self::Numeric

Return the bits as a number type.

impl Type for MessageFlags

fn signature() -> Signature<'static>

Get the signature for the implementing type.

impl Copy for MessageFlags

impl Eq for MessageFlags

impl StructuralPartialEq for MessageFlags
