[−][src]Struct pgx::datum::Array
Implementations
impl<'a, T: FromDatum> Array<'a, T>[src]
pub unsafe fn over(
elements: *mut Datum,
nulls: *mut bool,
nelems: usize
) -> Array<'a, T>[src]
elements: *mut Datum,
nulls: *mut bool,
nelems: usize
) -> Array<'a, T>
Create an Array over an array of pg_sys::Datum values and a corresponding array
of "is_null" indicators
[T] can be pg_sys::Datum if the elements are not all of the same type
Safety
This function is unsafe as it can't validate the provided pointer are valid or that

impl<'a, T: FromDatum> Iterator for ArrayTypedIterator<'a, T> type Item = T;Return an Iterator of the contained Datums (converted to Rust types).
This function will panic when called if the array contains any SQL NULL values.
