Struct CopyReader 

Source 
pub struct CopyReader<'a, F: ConnectionFactory> { /* private fields */ }

Implementations§

Source§

impl<'a, F: ConnectionFactory> CopyReader<'a, F>

Source

pub async fn read(&mut self) -> Result<Option<CopyData<'_>>, ElefantClientError>

Source

pub async fn finish(&mut self) -> Result<(), ElefantClientError>

Non-consuming cleanup: reads trailing protocol messages after CopyDone. Call this after read() returns None to leave the connection in a clean state.

Source

pub async fn end(self) -> Result<(), ElefantClientError>

Source

pub async fn write_to<W: ConnectionFactory>( self, target: &mut CopyWriter<'_, W>, ) -> Result<(), ElefantClientError>
