sourcepub fn new(writer: CopyInWriter<'a>, types: &[Type]) -> BinaryCopyInWriter<'a>
pub fn new(writer: CopyInWriter<'a>, types: &[Type]) -> BinaryCopyInWriter<'a>
Creates a new writer which will write rows of the provided types.
sourcepub fn write(&mut self, values: &[&(dyn ToSql + Sync)]) -> Result<(), Error>
pub fn write(&mut self, values: &[&(dyn ToSql + Sync)]) -> Result<(), Error>
Writes a single row.
