The Dap2 trait defines the necessary methods for serving a data-source (containing many variables, or datasets in HDF5 terms) over the DAP2 protocol. Additionally the dods::Dods trait which is implemented for sources implementing this trait handles the streaming a DODS response of several constrained variables.

Required Methods

fn das<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = &Das> + Send + 'async_trait>>

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

Return a reference to a DAS structure for a data-source.

fn dds<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = &Dds> + Send + 'async_trait>>

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

Return a reference to a DDS structure for a data-source.

fn variable<'life0, 'life1, 'async_trait>( &'life0 self, variable: &'life1 DdsVariableDetails, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<Bytes, Error>> + Send + 'static>>, Error>> + Send + 'async_trait>>

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

Stream the bytes of the variable in XDR (big-endian) format.

fn raw<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(u64, Pin<Box<dyn Stream<Item = Result<Bytes, Error>> + Send + 'static>>), Error>> + Send + 'async_trait>>

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

Stream the raw file (if supported). Should return a tuple with the content-length and a stream of Bytes.
