--- | The \`Status\` type defines a logical error model that is suitable for
--- different programming environments, including REST APIs and RPC APIs. It
--- is used by [gRPC](https:\/\/github.com\/grpc). The error model is
--- designed to be: - Simple to use and understand for most users - Flexible
--- enough to meet unexpected needs # Overview The \`Status\` message
--- contains three pieces of data: error code, error message, and error
--- details. The error code should be an enum value of [google.rpc.Code][],
--- but it may accept additional error codes if needed. The error message
--- should be a developer-facing English message that helps developers
--- *understand* and *resolve* the error. If a localized user-facing error
--- message is needed, put the localized message in the error details or
--- localize it in the client. The optional error details may contain
--- arbitrary information about the error. There is a predefined set of
--- error detail types in the package \`google.rpc\` which can be used for
--- common error conditions. # Language mapping The \`Status\` message is
--- the logical representation of the error model, but it is not necessarily
--- the actual wire format. When the \`Status\` message is exposed in
--- different client libraries and different wire protocols, it can be
--- mapped differently. For example, it will likely be mapped to some
--- exceptions in Java, but more likely mapped to some error codes in C. #
--- Other uses The error model and the \`Status\` message can be used in a
--- variety of environments, either with or without APIs, to provide a
--- consistent developer experience across different environments. Example
--- uses of this error model include: - Partial errors. If a service needs
--- to return partial errors to the client, it may embed the \`Status\` in
--- the normal response to indicate the partial errors. - Workflow errors. A
--- typical workflow has multiple steps. Each step may have a \`Status\`
--- message for error reporting purpose. - Batch operations. If a client
--- uses batch request and batch response, the \`Status\` message should be
--- used directly inside batch response, one for each error sub-response. -
--- Asynchronous operations. If an API call embeds asynchronous operation
--- results in its response, the status of those operations should be
--- represented directly using the \`Status\` message. - Logging. If some
--- API errors are stored in logs, the message \`Status\` could be used
--- directly after any stripping needed for security\/privacy reasons.

--- chooses to split again using stop_position, only stop_positions in [A,
--- C) will be accepted. * Etc. dynamic_source_split has similar semantics:
--- e.g., if a task with source S splits using dynamic_source_split into {P,
--- R} (where P and R must be together equivalent to S), then subsequent
--- progress and proposed_stop_position should be interpreted relative to P,
--- and in a potential subsequent dynamic_source_split into {P\', R\'}, P\'

--- some source, parsing the collection\'s elements. * Validate the
--- elements. * Apply a user-defined function to map each element to some
--- value and extract an element-specific key value. * Group elements with
--- the same key into a single element with that key, transforming a
--- multiply-keyed collection into a uniquely-keyed collection. * Write the
--- elements out to some data sink. (Note that the Dataflow service may be

+-- | The \`Status\` type defines a logical error model that is suitable for
+-- different programming environments, including REST APIs and RPC APIs. It
+-- is used by [gRPC](https:\/\/github.com\/grpc). The error model is
+-- designed to be: - Simple to use and understand for most users - Flexible
+-- enough to meet unexpected needs # Overview The \`Status\` message
+-- contains three pieces of data: error code, error message, and error
+-- details. The error code should be an enum value of google.rpc.Code, but
+-- it may accept additional error codes if needed. The error message should
+-- be a developer-facing English message that helps developers *understand*
+-- and *resolve* the error. If a localized user-facing error message is
+-- needed, put the localized message in the error details or localize it in
+-- the client. The optional error details may contain arbitrary information
+-- about the error. There is a predefined set of error detail types in the
+-- package \`google.rpc\` which can be used for common error conditions. #
+-- Language mapping The \`Status\` message is the logical representation of
+-- the error model, but it is not necessarily the actual wire format. When
+-- the \`Status\` message is exposed in different client libraries and
+-- different wire protocols, it can be mapped differently. For example, it
+-- will likely be mapped to some exceptions in Java, but more likely mapped
+-- to some error codes in C. # Other uses The error model and the
+-- \`Status\` message can be used in a variety of environments, either with
+-- or without APIs, to provide a consistent developer experience across
+-- different environments. Example uses of this error model include: -
+-- Partial errors. If a service needs to return partial errors to the
+-- client, it may embed the \`Status\` in the normal response to indicate
+-- the partial errors. - Workflow errors. A typical workflow has multiple
+-- steps. Each step may have a \`Status\` message for error reporting
+-- purpose. - Batch operations. If a client uses batch request and batch
+-- response, the \`Status\` message should be used directly inside batch
+-- response, one for each error sub-response. - Asynchronous operations. If
+-- an API call embeds asynchronous operation results in its response, the
+-- status of those operations should be represented directly using the
+-- \`Status\` message. - Logging. If some API errors are stored in logs,
+-- the message \`Status\` could be used directly after any stripping needed
+-- for security\/privacy reasons.
