| -// |MojoResult|: Result codes for Mojo operations. Non-negative values are

|
| -// |MOJO_RESULT_OK| - Not an error; returned on success. Note that positive
|
| -// |MojoResult|s may also be used to indicate success.
|
| -// |MOJO_RESULT_CANCELLED| - Operation was cancelled, typically by the caller.
|
| -// |MOJO_RESULT_UNKNOWN| - Unknown error (e.g., if not enough information is
|
| -// available for a more specific error).
|
| -// |MOJO_RESULT_INVALID_ARGUMENT| - Caller specified an invalid argument. This
|
| -// differs from |MOJO_RESULT_FAILED_PRECONDITION| in that the former
|
| -// indicates arguments that are invalid regardless of the state of the
|
| -// system.
|
| -// |MOJO_RESULT_DEADLINE_EXCEEDED| - Deadline expired before the operation
|
| -// could complete.
|
| -// |MOJO_RESULT_NOT_FOUND| - Some requested entity was not found (i.e., does
|
| -// not exist).
|
| -// |MOJO_RESULT_ALREADY_EXISTS| - Some entity or condition that we attempted
|
| -// to create already exists.
|
| -// |MOJO_RESULT_PERMISSION_DENIED| - The caller does not have permission to
|
| -// for the operation (use |MOJO_RESULT_RESOURCE_EXHAUSTED| for rejections
|
| -// caused by exhausting some resource instead).
|
| -// |MOJO_RESULT_RESOURCE_EXHAUSTED| - Some resource required for the call
|
| -// (possibly some quota) has been exhausted.
|
| -// |MOJO_RESULT_FAILED_PRECONDITION| - The system is not in a state required
|
| -// for the operation (use this if the caller must do something to rectify
|
| -// the state before retrying).
|
| -// |MOJO_RESULT_ABORTED| - The operation was aborted by the system, possibly
|
| -// due to a concurrency issue (use this if the caller may retry at a
|
| -// higher level).
|
| -// |MOJO_RESULT_OUT_OF_RANGE| - The operation was attempted past the valid
|
| -// range. Unlike |MOJO_RESULT_INVALID_ARGUMENT|, this indicates that the
|
| -// operation may be/become valid depending on the system state. (This
|
| -// error is similar to |MOJO_RESULT_FAILED_PRECONDITION|, but is more
|
| -// specific.)
|
| -// |MOJO_RESULT_UNIMPLEMENTED| - The operation is not implemented, supported,
|
| -// or enabled.
|
| -// |MOJO_RESULT_INTERNAL| - Internal error: this should never happen and
|
| -// indicates that some invariant expected by the system has been broken.
|
| -// |MOJO_RESULT_UNAVAILABLE| - The operation is (temporarily) currently
|
| -// unavailable. The caller may simply retry the operation (possibly with a
|
| -// backoff).
|
| -// |MOJO_RESULT_DATA_LOSS| - Unrecoverable data loss or corruption.
|
| -// |MOJO_RESULT_BUSY| - One of the resources involved is currently being used
|
| -// (possibly on another thread) in a way that prevents the current
|
| -// operation from proceeding, e.g., if the other operation may result in
|
| -// the resource being invalidated.
|
| -// |MOJO_RESULT_SHOULD_WAIT| - The request cannot currently be completed
|
| -// (e.g., if the data requested is not yet available). The caller should
|
| -// wait for it to be feasible using |MojoWait()| or |MojoWaitMany()|.
|
| -//
|
| -// Note that positive values are also available as success codes.
|
| -//
|
| -// The codes from |MOJO_RESULT_OK| to |MOJO_RESULT_DATA_LOSS| come from
|
| -// Google3's canonical error codes.
|
| -//
|
| -// TODO(vtl): Add a |MOJO_RESULT_UNSATISFIABLE|?
