Expand description

宿主 REST 桥的独立调用策略;共享发现时效仅由 snapshot 策略裁决。

Fields§

§request_timeout_ms: u64

一次请求的最大耗时,单位为毫秒。

§connect_timeout_ms: u64

HTTP 建连预算,单位为毫秒,不得超过请求总预算。

§lb_strategy: String

实例选择策略,可使用 round_robin 或 weighted。

§instance_scheme: String

发现实例的 HTTP 协议,只接受 http 或 https。

§retry_get_head_on_transport_error: bool

是否允许 GET/HEAD 在传输错误后按剩余预算重试。

§retry_get_head_on_retryable_status: bool

是否允许 GET/HEAD 在可重试响应状态后重试。

§max_attempts: usize

一次逻辑请求允许的总尝试次数,包含首次调用。

Implementations§

impl RestPolicy

Source

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

业务作用:在连接准备前拒绝非法调用时长、协议、分配策略和重试次数。 参数说明:无。 返回:策略有效时成功;不开放任意 HTTP 方法的自动重试。
