Derive Macro SecureSerialize 

#[derive(SecureSerialize)]
{
    // Attributes available to this derive:
    #[redact]
    #[secure_serialize]
}

Derives SecureSerialize for a struct.

Fields marked with #[redact] or #[redact(with = "...")] will be redacted when serialized.

Field attributes

• #[redact] — Redact with default "<redacted>"
• #[redact(with = "***")] — Redact with custom string "***"

Struct attributes

• #[secure_serialize(debug)] — Generate fmt::Debug with redacted fields (declaration order).
• #[secure_serialize(display)] — Generate fmt::Display as compact redacted JSON.
• #[secure_serialize(debug, display)] — Both.

Example

#[derive(SecureSerialize, Deserialize)]
#[secure_serialize(debug, display)]
struct Config {
    pub host: String,
    #[redact]
    pub api_key: String,
    #[redact(with = "***")]
    pub password: String,
}
