Implementations§

Source§

impl<TCustom> Message<TCustom>
where TCustom: MsgDataBound,

Source

pub fn new(data: MsgData<TCustom>) -> Self

Создать новое сообщение

Source

pub fn new_custom(custom_data: TCustom) -> Self

Создать новое сообщение типа MsgData::Custom

Source

pub fn get_custom_data(&self) -> Option<TCustom>

Возвращает данные сообщения, если тип сообщения MsgData::Custom

Source

pub fn add_trace_item(&mut self, id: &Uuid)

Добавить запись пути

Source

pub fn contains_trace_item(&self, id: &Uuid) -> bool

Проверяем, что в трейсе сообщения присутсвует компонент с заданным id.

Полезно для предотварщения зацикливания сообщений, чтобы данный компонент не обрабатывал сообщения, которые он же и сгенерировал

Source

pub fn update_time_to_live(&mut self, time_step: Duration)

Обновить время жизни сообщения

Source

pub fn is_alive(&self) -> bool

Возвращает false, если время жизни сообщения истекло

Source

pub fn service_origin(&self) -> String

Возращает название сервиса, в котором было создано данное сообщение. Паникует, если название сервиса еще не установлено

Source

pub fn set_service_origin(&mut self, service: &str)

Устанавливает название сервиса, в котором было создано данное сообщение. Если название уже установлено, то пропускаем

Source

pub fn is_route_enabled( &self, src: &TCustom::TService, dst: &TCustom::TService, ) -> bool

Разрешен ли марштур данного сообщения

Source§

impl<TData> Message<TData>
where TData: DeserializeOwned + Serialize,

Source

pub fn serialize(&self) -> Result<String, Error>

Сериализация сообщений в json

Source

pub fn serialize_json_pretty(&self) -> Result<String, Error>

Сериализация сообщений в json

Source

pub fn serialize_data(&self) -> Result<String, Error>

Сериализация полей данных сообщений в json

Source

pub fn deserialize(text: &str) -> Result<Self, Error>

Десериализация одного сообщения из json

Source

pub fn deserialize_many(text: &str) -> Result<Vec<Self>, Error>

Десериализация массива сообщений из json
