Trait AsyncReaderFactory

pub trait AsyncReaderFactory {
    // Required method
    fn get_reader<'a, 'async_trait>(
        &'a mut self,
    ) -> Pin<Box<dyn Future<Output = Result<Box<dyn AsyncRead + Sync + Send + Unpin + 'static>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'a: 'async_trait;
}

An AsyncReaderFactory can produce, on demand, an AsyncRead object. In the event of an upload failure, the restarted upload will use a fresh reader to start reading object content at the beginning.

Required Methods

fn get_reader<'a, 'async_trait>( &'a mut self, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn AsyncRead + Sync + Send + Unpin + 'static>>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait,

Get a fresh AsyncRead object, positioned at the beginning of the data to be uploaded.
