Struct postgres::binary_copy::BinaryCopyInWriter
source · [−]pub struct BinaryCopyInWriter<'a> { /* private fields */ }Expand description
A type which serializes rows into the PostgreSQL binary copy format.
The copy must be explicitly completed via the finish method. If it is not, the copy will be aborted.
Implementations
sourceimpl<'a> BinaryCopyInWriter<'a>
impl<'a> BinaryCopyInWriter<'a>
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.
Panics
Panics if the number of values provided does not match the number expected.
sourcepub fn write_raw<P, I>(&mut self, values: I) -> Result<(), Error> where
P: BorrowToSql,
I: IntoIterator<Item = P>,
I::IntoIter: ExactSizeIterator,
pub fn write_raw<P, I>(&mut self, values: I) -> Result<(), Error> where
P: BorrowToSql,
I: IntoIterator<Item = P>,
I::IntoIter: ExactSizeIterator,
A maximally-flexible version of write.
Panics
Panics if the number of values provided does not match the number expected.
