Logs: LogRecord not documented, usage attempt fails with an exception #3552
Description
Describe your environment
Mac OS X
Python 3.9.6
Steps to reproduce
Try to use LogRecord described here: https://opentelemetry-python.readthedocs.io/en/latest/api/_logs.html#opentelemetry._logs.LogRecord
The docs don't say how to construct the LogRecord. I tried this:
logger_provider = LoggerProvider(
resource=Resource.create(
{
"service.name": "shoppingcart",
"service.instance.id": "instance-12",
}
),
)
set_logger_provider(logger_provider)
_logger = _logs.get_logger("bridge-logger")
logRecord = _logs.LogRecord()
_logger.emit(logRecord)What is the expected behavior?
An empty log record outputed.
What is the actual behavior?
Exception while exporting logs.

AttributeError: 'LogRecord' object has no attribute 'resource'
I can't see a way to supply the 'resource', the LogRecord() constructor does not accept one. Besides, I should not need to, it should use the one given to LoggerProvider.
