Struct SagaPayloadContract 

pub struct SagaPayloadContract {
    pub content_type: String,
    pub schema_id: String,
}

业务作用：把媒体类型与 schema 身份绑定到步骤定义，禁止端点轮换改变正文解释规则。

Fields

content_type: String

小写规范媒体类型，不包含传输参数。

schema_id: String

业务 schema 的稳定身份；无 schema 的 JSON 使用空字符串。

Implementations

impl SagaPayloadContract

pub fn validate(&self) -> Result<(), SagaPayloadError>

业务作用：验证媒体类型与 schema 的规范形式，避免签名或摘要接受等价别名。

参数说明: 无。

返回：字段规范且二进制正文具有 schema 身份时成功，否则返回稳定拒绝。
