Trait ReadListener 

pub trait ReadListener<I>: Send + Sync {
    // Provided methods
    fn before_read<'a>(
        &'a self,
        context: ItemListenerContext<'a>,
    ) -> BoxFuture<'a, Result<(), ListenerError>> { ... }
    fn after_read<'a>(
        &'a self,
        item: &'a I,
        context: ItemListenerContext<'a>,
    ) -> BoxFuture<'a, Result<(), ListenerError>> { ... }
    fn on_read_error<'a>(
        &'a self,
        fault: FaultDescriptor,
        context: ItemListenerContext<'a>,
    ) -> BoxFuture<'a, Result<(), ListenerError>> { ... }
}

Observes reader invocations for one item.

Provided Methods

fn before_read<'a>( &'a self, context: ItemListenerContext<'a>, ) -> BoxFuture<'a, Result<(), ListenerError>>

Runs in registration order before the reader is invoked.

fn after_read<'a>( &'a self, item: &'a I, context: ItemListenerContext<'a>, ) -> BoxFuture<'a, Result<(), ListenerError>>

Runs in reverse registration order after one item is read.

fn on_read_error<'a>( &'a self, fault: FaultDescriptor, context: ItemListenerContext<'a>, ) -> BoxFuture<'a, Result<(), ListenerError>>

Runs in reverse registration order for every failed reader call.

This includes a call that a later retry completes successfully.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
