Trait miniconf::TreeSerialize
source · pub trait TreeSerialize {
// Required method
fn serialize_by_key<K, S>(
&self,
keys: K,
ser: S,
) -> Result<usize, Error<S::Error>>
where K: Keys,
S: Serializer;
}Expand description
Serialize a leaf node by its keys.
See also crate::json or crate::postcard for convenient functions using these traits.
§Derive macro
crate::TreeSerialize derives TreeSerialize for structs with named fields and tuple structs
and for enums with newtype and unit variants.
The field attributes are described in the TreeKey trait.
