Struct CopyIn

Source 
pub struct CopyIn<'a, C>
where
    C: Copy + Send,
{ /* private fields */ }

Implementations§

Source§

impl<'a, C> CopyIn<'a, C>
where C: Copy + Send,

Source

pub fn new( client: &'a mut C, stmt: &Statement, ) -> impl Future<Output = Result<Self, Error>> + Send

Source

pub fn copy(&mut self, item: impl Buf) -> Result<(), Error>

copy given buffer into Driver and send it to database in non blocking manner

*. calling this api in rapid succession and/or supply huge buffer may result in high memory consumption. consider rate limiting the progress with small chunk of buffer and/or using smart pointers for throughput counting

Source

pub async fn finish(self) -> Result<u64, Error>

finish copy in and return how many rows are affected
