Source trait defines the interface for data sources

Required Methods

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

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

Initialize the source

fn next<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = StreamResult<Option<Record<T>>>> + Send + 'async_trait>>

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

Read the next record from the source

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

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

Close the source and release resources

Implementors
