[−][src]Trait pgx::datum::IntoDatum

pub trait IntoDatum {
    fn into_datum(self) -> Option<Datum>;

    fn type_oid() -> Oid;

    fn array_type_oid() -> Oid { ... }
}

Convert a Rust type into a pg_sys::Datum.

Default implementations are provided for the common Rust types.

If implementing this, also implement FromDatum for the reverse conversion.

Note that any conversions that need to allocate memory (ie, for a varlena * representation of a Rust type, that memory must be allocated within a [PgMemoryContext]
