CircuitBreaker is created for each ExecutorPool to track whether requests should be attempted, or rejected if the Health of the circuit is too low.

A CircuitError is an error which models various failure states of execution, such as the circuit being open or a timeout.

CommandConfig is used to tune circuit settings at runtime

DatadogClient is the minimum interface needed by NewDatadogCollectorWithClient

DatadogCollector fulfills the metricCollector interface allowing users to ship circuit stats to Datadog. This Collector, by default, uses github.com/

DefaultMetricCollector holds information about the circuit state. This implementation of MetricCollector is the canonical source of information about

GraphiteCollector fulfills the metricCollector interface allowing users to ship circuit stats to a graphite backend. To use users must call Initialize

GraphiteCollectorConfig provides configuration that the graphite client will need.

MetricCollector represents the contract that all collectors must fulfill to gather circuit statistics. Implementations of this interface do not have t

NoopLogger does not log anything.

Number tracks a numberBucket over a bounded number of time buckets. Currently the buckets are one second long and only the last 10 seconds are kept.

StatsdCollector fulfills the metricCollector interface allowing users to ship circuit stats to a Statsd backend. To use users must call InitializeStat

StatsdCollectorConfig provides configuration that the Statsd client will need.

StreamHandler publishes metrics for each command and each pool once a second to all connected HTTP client.

Timing maintains time Durations for each time bucket. The Durations are kept in an array to allow for a variety of statistics to be calculated from th

command models the state used for a single execution on a circuit. "hystrix command" is commonly used to describe the pairing of your run/fallback fun
