Struct FieldEncryptionConfig 

pub struct FieldEncryptionConfig {
    pub columns: HashMap<String, FieldEncryptionKey>,
}

Configuration for field-level encryption in the segment writer.

Maps column names to encryption keys. Only columns listed here are encrypted; all other columns remain in plaintext.

Fields

columns: HashMap<String, FieldEncryptionKey>

Column name → encryption key mapping.
