<p>Operation was rejected because the system is not in a state required for the operation's execution. </p>
<p>For example, directory to be deleted may be non-empty, an rmdir operation is applied to a non-directory, etc.</p>
<p>A litmus test that may help a service implementor in deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE: (a) Use UNAVAILABLE if the client can retry just the failing call. (b) Use ABORTED if the client should retry at a higher-level (e.g., restarting a read-modify-write sequence). (c) Use FAILED_PRECONDITION if the client should not retry until the system state has been explicitly fixed. E.g., if an "rmdir" fails because the directory is non-empty, FAILED_PRECONDITION should be returned since the client should not retry unless they have first fixed up the directory by deleting files from it. (d) Use FAILED_PRECONDITION if the client performs conditional REST Get/Update/Delete on a resource and the resource on the server does not match the condition. E.g., conflicting read-modify-write on the same resource. </p>

<p>Operation was attempted past the valid range. </p>
<p>E.g., seeking or reading past end of file.</p>
<p>Unlike INVALID_ARGUMENT, this error indicates a problem that may be fixed if the system state changes. For example, a 32-bit file system will generate INVALID_ARGUMENT if asked to read at an offset that is not in the range [0,2^32-1], but it will generate OUT_OF_RANGE if asked to read from an offset past the current file size.</p>
<p>There is a fair bit of overlap between FAILED_PRECONDITION and OUT_OF_RANGE. We recommend using OUT_OF_RANGE (the more specific error) when it applies so that callers who are iterating through a space can easily look for an OUT_OF_RANGE error to detect when they are done. </p>
