pub fn tables_last<'a, I, K, V, S>(
data: &'a I,
serializer: S,
) -> Result<S::Ok, S::Error>
Expand description
Convenience function to serialize items in a map in an order valid with TOML.
TOML carries the restriction that keys in a table must be serialized last if their value is a table itself. This isn’t always easy to guarantee, so this helper can be used like so:
#[derive(Serialize)]
struct Manifest {
package: Package,
#[serde(serialize_with = "toml::ser::tables_last")]
dependencies: HashMap<String, Dependency>,
}
