class MakeErrorStream

class MakeErrorStream

Defined at line 34 of file ../../third_party/cobalt/src/public/lib/statusor/status_macros.h

Stream object used to collect error messages in MAKE_ERROR macros

or append error messages with APPEND_ERROR. It accepts any

arguments with operator

<

<

to build an error string, and then has an

implicit cast operator to Status, which converts the

logged string to a Status object and returns it, after logging the

error. At least one call to operator

<

<

is required; a compile time

error will be generated if none are given. Errors will only be

logged by default for certain status codes, as defined in

IsLoggedByDefault. This class will give ERROR errors if you don't

retrieve a Status exactly once before destruction.

The class converts into an intermediate wrapper object

MakeErrorStreamWithOutput to check that the error stream gets at least one

item of input.
