Trait MessageBus 

pub trait MessageBus:
    Send
    + Sync
    + Clone
    + 'static {
    // Required methods
    fn publish<'life0, 'async_trait>(
        &'life0 self,
        subject: String,
        payload: Bytes,
    ) -> Pin<Box<dyn Future<Output = Result<(), PublishError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
    fn request<'life0, 'async_trait>(
        &'life0 self,
        subject: String,
        payload: Bytes,
    ) -> Pin<Box<dyn Future<Output = Result<Message, RequestError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

A trait abstraction over message bus (e.g. NATS) interactions.

Required Methods

fn publish<'life0, 'async_trait>( &'life0 self, subject: String, payload: Bytes, ) -> Pin<Box<dyn Future<Output = Result<(), PublishError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Publishes a message to a given subject.

fn request<'life0, 'async_trait>( &'life0 self, subject: String, payload: Bytes, ) -> Pin<Box<dyn Future<Output = Result<Message, RequestError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Sends a request message to a given subject and waits for a response.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl MessageBus for Client

fn publish<'life0, 'async_trait>( &'life0 self, subject: String, payload: Bytes, ) -> Pin<Box<dyn Future<Output = Result<(), PublishError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

fn request<'life0, 'async_trait>( &'life0 self, subject: String, payload: Bytes, ) -> Pin<Box<dyn Future<Output = Result<Message, RequestError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,
