	LeaseAccessConditions *LeaseAccessConditions
	// LeaseAction describes actions that can be performed on a lease.
	LeaseAction *LeaseAction
	// LeaseDuration specifies the duration of the lease, in seconds, or negative one
	// (-1) for a lease that never expires. A non-infinite lease can be between 15 and 60 seconds.
	LeaseDuration *int64
	// ProposedLeaseID specifies the proposed lease ID for the file.
	ProposedLeaseID *string
	// CPKInfo contains optional parameters to perform encryption using customer-provided key.
	CPKInfo *CPKInfo
	// Flush Optional. If true, the file will be flushed after append.
	Flush *bool
}

AppendDataOptions contains the optional parameters for the Client.AppendData method.

type AppendDataResponse 

type AppendDataResponse = generated.PathClientAppendDataResponse

	// TreatEarlyCloseAsError is true, then retryReader's special behaviour is suppressed, and "read on closed body" is instead
	// treated as a fatal (non-retryable) error.
	// Note that setting TreatEarlyCloseAsError only guarantees that Closing will produce a fatal error if the Close happens
	// from the same "thread" (goroutine) as Read.  Concurrent Close calls from other goroutines may instead produce network errors
	// which will be retried.
	// The default value is false.
