Struct SingleTransportStatus 

pub(crate) struct SingleTransportStatus {
    pub(crate) last_failure: Option<Instant>,
    pub(crate) consecutive_failures: usize,
    pub(crate) consecutive_rate_limits: usize,
    pub(crate) rate_limited_until: Option<Instant>,
    pub(crate) shutting_down: bool,
}

The status of a single transport

Fields

last_failure: Option<Instant>

consecutive_failures: usize

consecutive_rate_limits: usize

rate_limited_until: Option<Instant>

shutting_down: bool

Whether or not this current transport is being shut down (switching to the next transport)

Implementations

impl SingleTransportStatus

fn log_success(&mut self)

Log a successful call to the inner transport

fn log_rate_limit(&mut self, until: Instant) -> bool

Log a rate limit from the inner transport, backing off until until. Returns whether or not the transport should be switched to the next URL.

One rate limit is not a provider fault: the caller backs off and retries. One that outlives a backoff is, because every request inside the backoff window short-circuits without reaching the provider, and nothing else in call moves off it: should_revert only reverts towards the primary.

Only a rate limit arriving outside a backoff window counts. Requests already in flight when the window opened tell us nothing new, and would otherwise reach MAX_CONSECUTIVE_RATE_LIMITS in a single burst with no backoff having elapsed at all.

fn log_failure(&mut self, opt: &L1ClientOptions) -> bool

Log a failure to call the inner transport. Returns whether or not the transport should be switched to the next URL

fn should_switch(&mut self, opt: &L1ClientOptions) -> bool

Whether or not the transport should be switched to the next URL

fn should_revert(&mut self, revert_at: Option<Instant>) -> bool

Whether or not the transport should be switched back to the primary URL.
