Struct SagaHttpCredentials 

Source
pub struct SagaHttpCredentials { /* private fields */ }
Expand description

业务作用:保存当前出站 HMAC 与仅在重叠窗口内允许入站验签的历史材料。

Implementations§

Source§

impl SagaHttpCredentials

Source

pub fn from_hex_key(hex_key: &str) -> Result<Self, SagaHttpMessageAuthError>

业务作用:在配置准备阶段校验 HMAC 材料,避免无效候选影响当前请求。 参数说明:hex_key 必须是 256 位小写十六进制 key。 返回:合法材料对应的不可变凭据快照;非法编码返回脱敏配置错误。

Source

pub fn rotated( &self, hex_key: &str, overlap: Duration, ) -> Result<Self, SagaHttpMessageAuthError>

业务作用:准备新出站凭据并保留有界的旧入站验签窗口,候选未发布时不改变当前权威。 参数说明:hex_key 是新材料,overlap 为本地单调时钟上的旧 key 保留期限,最长一小时。 返回:完整候选快照;非法 key、零期限或超过八份仍有效的旧材料时拒绝候选,不提前丢弃旧窗口。

Source

pub fn current_result_contract(&self) -> &str

业务作用:让 capability 绑定当前实际出站 key 的不可逆合同摘要,避免 Registry 凭据掩盖结果凭据错配。 参数说明:无。 返回:当前 HMAC 材料的域分离 SHA-256,不暴露 key 或可重放的请求签名。

Source

pub fn accepted_result_contracts(&self) -> BTreeSet<String>

业务作用:让 Catalog 使用与入站验签相同的旧 key 截止时刻判断结果凭据是否可接受。 参数说明:无。 返回:当前与尚在重叠窗口内的合同摘要;过期旧 key 不进入激活证据。
