sourceimpl<'a, E> DatumType<'a, E> for VarChar<&'a str>
impl<'a, E> DatumType<'a, E> for VarChar<&'a str>
sourcefn try_from_result(
res: Result<Datum<'a>, E>
) -> Result<Self, Result<Datum<'a>, E>>
fn try_from_result(
res: Result<Datum<'a>, E>
) -> Result<Self, Result<Datum<'a>, E>>
Try to convert a Result whose Ok variant is a Datum into this native Rust type (Self). If it fails the error variant will contain the original result. Read more
sourcefn into_result(self, _temp_storage: &'a RowArena) -> Result<Datum<'a>, E>
fn into_result(self, _temp_storage: &'a RowArena) -> Result<Datum<'a>, E>
Convert this Rust type into a Result containing a Datum, or an error
