Struct Topic 

pub struct Topic {
    pub namespace: String,
    pub entity_type: String,
    pub entity: String,
    pub sub_entity: Option<String>,
    pub action: String,
}

A topic clearly defines the target of the event and its structure is similar to a REST URI, except the last part, the action.

See https://www.openhab.org/docs/developer/utils/events.html#the-core-events.

Fields

namespace: String

entity_type: String

entity: String

sub_entity: Option<String>

GroupItemStateChangedEvent has an additional topic part

action: String

Trait Implementations

impl Clone for Topic

fn clone(&self) -> Topic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Topic

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

Formats the value using the given formatter.

impl Default for Topic

fn default() -> Topic

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Topic

where Self: FromStr, <Self as FromStr>::Err: Display,

fn deserialize<__D>(deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Topic

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

Formats the value using the given formatter.

impl FromStr for Topic

type Err = HabRsError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Topic

fn eq(&self, other: &Topic) -> 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 Serialize for Topic

where Self: Display,

fn serialize<__S>(&self, serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
