Struct zbus::OwnedMatchRule

pub struct OwnedMatchRule(_);

Owned sibling of MatchRule.

Implementations

impl OwnedMatchRule

pub fn into_inner(self) -> MatchRule<'static>

Convert to the inner MatchRule, consuming self.

pub fn inner(&self) -> &MatchRule<'static>

Get a reference to the inner MatchRule.

Methods from Deref<Target = MatchRule<'static>>

pub fn sender(&self) -> Option<&BusName<'_>>

The sender, if set.

pub fn msg_type(&self) -> Option<MessageType>

The message type, if set.

pub fn interface(&self) -> Option<&InterfaceName<'_>>

The interfac, if set.

pub fn member(&self) -> Option<&MemberName<'_>>

The member name if set.

pub fn path_spec(&self) -> Option<&MatchRulePathSpec<'_>>

The path or path namespace, if set.

pub fn destination(&self) -> Option<&UniqueName<'_>>

The destination, if set.

pub fn args(&self) -> &[(u8, Str<'_>)]

The arguments.

pub fn arg_paths(&self) -> &[(u8, ObjectPath<'_>)]

The argument paths.

pub fn arg0namespace(&self) -> Option<&InterfaceName<'_>>

Match messages whose first argument is within the specified namespace.

Note that while the spec allows this to be any string that’s a valid bus or interface name except that it can have no ., we only allow valid interface names. The reason is not only to keep things simple and type safe at the same time but also for the fact that use cases of only matching on the first component of a bus or interface name are unheard of.

pub fn to_owned(&self) -> MatchRule<'static>

Creates an owned clone of self.

pub fn matches(&self, msg: &Message) -> Result<bool>

Match the given message against this rule.

Caveats

Since this method doesn’t have any knowledge of names on the bus (or even connection to a bus) matching always succeeds for:

• sender in the rule (if set) that is a well-known name. The sender on a message is always a unique name.
• destination in the rule when destination on the msg is a well-known name. The destination on match rule is always a unique name.

Trait Implementations

impl Clone for OwnedMatchRule

fn clone(&self) -> OwnedMatchRule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OwnedMatchRule

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

Formats the value using the given formatter.

impl Deref for OwnedMatchRule

type Target = MatchRule<'static>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for OwnedMatchRule

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'unowned, 'owned: 'unowned> From<&'owned OwnedMatchRule> for MatchRule<'unowned>

fn from(rule: &'owned OwnedMatchRule) -> Self

Converts to this type from the input type.

impl From<MatchRule<'_>> for OwnedMatchRule

fn from(rule: MatchRule<'_>) -> Self

Converts to this type from the input type.

impl From<OwnedMatchRule> for MatchRule<'static>

fn from(o: OwnedMatchRule) -> Self

Converts to this type from the input type.

impl Hash for OwnedMatchRule

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<MatchRule<'_>> for OwnedMatchRule

fn eq(&self, other: &MatchRule<'_>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for OwnedMatchRule

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,
