class LogBuffer
Defined at line 86 of file ../../sdk/lib/syslog/structured_backend/cpp/log_buffer.h
Opaque structure representing the backend encode state.
This structure only has meaning to the backend and application code shouldn't
touch these values.
LogBuffers store the state of a log record that is in the process of being
encoded.
A LogBuffer is initialized by calling BeginRecord,
and is written to the LogSink by calling FlushRecord.
Calling BeginRecord on a LogBuffer will always initialize it to its
clean state.

buffer -- The buffer to initialize
severity -- The severity of the log
file_name -- The name of the file that generated the log message
line -- The line number that caused this message to be generated
message -- The message to output.
the message should be interpreted as a C-style printf before being displayed to the
user.
dropped_count -- Number of dropped messages
pid -- The process ID that generated the message.
tid -- The thread ID that generated the message.

cpp20::span<const uint8_t> EndRecord ()Ends the record and returns a span for it. This is safe to be called multiple times.
If an encoding error has occurred an empty span will be returned.
