compress time formate by time.RFC3339 failed, compressed byte slice len is 0 about lz4 HOT 4 CLOSED

As per the doc, if there is no error and the compressed size is 0, then the data is NOT compressible.
Let me know if the documentation needs refining, thanks.

my src []byte is {"CreatedAt":"2019-12-29T20:56:26.535143+08:00"}
so as the doc means，this kind of slice is NOT compressible?
but it is compressible when i use github.com/golang/snappy

Being not compressible here means that the compressed size would be bigger than the input one.
In which case, it is usually better to keep the original form.

See: https://play.golang.org/p/k8otsp5Zo-i
where the snappy output is bigger.

NB. I find the *Block functions usually not the be best option and use the Reader and Writer instead as all of this is handled for you and the LZ4 stream format overhead is minimal.

Does this make sense or do you need more?
