Trait AeronBlockHandlerCallback 

pub trait AeronBlockHandlerCallback {
    // Required method
    fn handle_aeron_block_handler(
        &mut self,
        buffer: &[u8],
        session_id: i32,
        term_id: i32,
    );
}

Callback for handling a block of messages being read from a log.

@param clientd passed to the block poll function. @param buffer containing the block of message fragments. @param offset at which the block begins, including any frame headers. @param length of the block in bytes, including any frame headers that is aligned. @param session_id of the stream containing this block of message fragments. @param term_id of the stream containing this block of message fragments.

(note you must copy any arguments that you use afterwards even those with static lifetimes)

Required Methods

fn handle_aeron_block_handler( &mut self, buffer: &[u8], session_id: i32, term_id: i32, )

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl AeronBlockHandlerCallback for AeronBlockHandlerLogger

impl AeronBlockHandlerCallback for NoHandler

impl<F: FnMut(&[u8], i32, i32)> AeronBlockHandlerCallback for F

Any closure with the matching signature is a callback: methods that retain it heap-allocate it into a Handler owned by the registering resource.

impl<T: AeronBlockHandlerCallback> AeronBlockHandlerCallback for Handler<T>

Pass an existing Handler clone anywhere a callback value is expected, e.g. to share one callback instance across several registrations.
