Trait BlobProvider

pub trait BlobProvider:
    Debug
    + Send
    + Sync {
    // Required method
    fn get_blob<'life0, 'life1, 'async_trait>(
        &'life0 self,
        blob_id: &'life1 str,
    ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Provides a way of retrieving blobs. Some implementations may not need it. In that case, they can return None in the get_blob method. It can be used as extra verification if you also store the blob yourself.

Required Methods

fn get_blob<'life0, 'life1, 'async_trait>( &'life0 self, blob_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns the blob for the given blob_id. If the blob is not found, it should return None.
