Function solana_sdk::deserialize_utils::default_on_eof

pub fn default_on_eof<'de, T, D>(d: D) -> Result<T, D::Error>where
    D: Deserializer<'de>,
    T: Deserialize<'de> + Default,

This helper function enables successful deserialization of versioned structs; new structs may include additional fields if they impl Default and are added to the end of the struct. Right now, this function is targeted at bincode deserialization; the error match may need to be updated if another package needs to be used in the future.
