impl PackageStream for Source

Source §

type Error = OpenError

Error occurring when interacting with the data source.

Source §

type FileStream = GetObjectOutput

This intermediate associated type is used here to avoid a return-position impl of the Self::open_file_header_stream method. If this method would have a return-position impl, the impl would capture the lifetime of &self and the compiler would require a ’static lifetime for &self:

Source §

async fn open_file_header_stream( &self, offset: u64, total_size: u64, ) -> Result<Self::FileStream, Either<HeaderParseError, Self::Error>>

Open the actual data at a given offset.
