Struct postgres::CopyInStatement

pub struct CopyInStatement<'a> {
    // some fields omitted
}

A prepared COPY FROM STDIN statement.

Methods

impl<'a> CopyInStatement<'a>

fn column_types(&self) -> &[Type]

Returns a slice containing the expected column types.

fn execute<I, J>(&self, rows: I) -> Result<u64> where I: Iterator<Item=J>, J: StreamIterator

Executes the prepared statement.

The rows argument is an Iterator returning StreamIterator values, each one of which provides values for a row of input. This setup is designed to allow callers to avoid having to maintain the entire row set in memory.

Returns the number of rows copied.

fn finish(self) -> Result<()>

Consumes the statement, clearing it from the Postgres session.

Functionally identical to the Drop implementation of the CopyInStatement except that it returns any error to the caller.
