Struct ProviderHealth 

#[non_exhaustive]
pub struct ProviderHealth {
    pub provider: Provider,
    pub is_healthy: bool,
    pub recent_successes: u32,
    pub recent_failures: u32,
    pub last_error: Option<String>,
    pub requests_remaining_estimate: Option<f64>,
}

Snapshot of one provider’s recent health and (where derivable) remaining rate-limit budget.

Purely observational — computed from the last WINDOW dispatch outcomes recorded in-process by [super::ProviderSet]; it is not a circuit breaker and does not itself change dispatch behavior (routing and RetryPolicy are unaffected by it).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

provider: Provider

The provider this snapshot describes.

is_healthy: bool

true when at least half of the recent recorded outcomes succeeded, or when no calls have been recorded yet (optimistic default).

recent_successes: u32

Successes among the last WINDOW recorded outcomes.

recent_failures: u32

Failures among the last WINDOW recorded outcomes.

last_error: Option<String>

The most recent failure’s message. Cleared by any success, so it is set only when the latest recorded outcome was a failure.

requests_remaining_estimate: Option<f64>

Best-effort estimate of remaining rate-limit budget (tokens in the adapter’s own token bucket), when the provider exposes one via super::ProviderAdapter::rate_limit_remaining. None for providers with no local rate limiter to peek (e.g. Yahoo) or that haven’t been initialized.
