Configuration Changes

// ReconciliationCoverage is used to add conditions
// to reconciliation coverage for exiting `check:data`.
// All provided conditions must be satisfied before
// the end condition is considered satisfied.
//
// If FromTip, Tip, Height, and AccountCount are not provided,
// `check:data` will halt as soon as coverage surpasses
// Coverage.
type ReconciliationCoverage struct {
	// Coverage is some value [0.0, 1.0] that represents
	// the % of accounts reconciled.
	Coverage float64 `json:"coverage"`

	// FromTip is a boolean indicating if reconciliation coverage
	// should only be measured from tip (i.e. reconciliations
	// performed at or after tip was reached).
	FromTip bool `json:"from_tip,omitempty"`

	// Tip is a boolean indicating that tip must be reached
	// before reconciliation coverage is considered valid.
	Tip bool `json:"tip,omitempty"`

	// Index is an int64 indicating the height that must be
	// reached before reconciliation coverage is considered valid.
	Index *int64 `json:"height,omitempty"`

	// AccountCount is an int64 indicating the number of accounts
	// that must be observed before reconciliation coverage is considered
	// valid.
	AccountCount *int64 `json:"account_count,omitempty"`
}
