_note_ : at the time of this writing, `--adapt` can remain stuck at low speed
when combined with multiple worker threads (>=2).
* `--stream-size=#` :
When handling input from a stream, `zstd` must guess how large the source size
will be when optimizing compression parameters. This option sets the pledged source
size of a stream to eliminate that guesswork. Note that the pledged size must be exact;
incorrect stream sizes will cause an error.
Sets the pledged source size of input coming from a stream. This value must be exact, as it
will be included in the produced frame header. Incorrect stream sizes will cause an error.
This information will be used to better optimize compression parameters, resulting in
better and potentially faster compression, especially for smaller source sizes.
* `--rsyncable` :
`zstd` will periodically synchronize the compression state to make the
compressed file more rsync-friendly. There is a negligible impact to
