pub trait AsChangeset {

type Changeset;
// Required method
fn as_changeset(self) -> Self::Changeset;
}Expand description
Types which can be passed to
update.set.
§Deriving
This trait can be automatically derived using by adding #[derive(AsChangeset)]
to your struct. Structs which derive this trait must be annotated with
#[table_name = "something"]. If the field name of your struct differs
from the name of the column, you can annotate the field with
#[column_name = "some_column_name"].
By default, any Option fields on the struct are skipped if their value is
None. If you would like to assign NULL to the field instead, you can
annotate your struct with #[changeset_options(treat_none_as_null = "true")].
