In led_strip; purpose of rmt_translator_set_context()?

[Xylopyrographer]

In the led_strip driver, led_strip_init() winds up calling rmt_translator_set_context() (if the IDF version falls within the range where the brightness of the strip is enabled).

I can't figure out what and am hoping someone can explain what exactly rmt_translator_set_context() does and why the strip descriptor is passed in the CHECK(rmt_translator_set_context(config.channel, strip)); call?

The purpose of the rmt_translator_set_context() call is obvious: this function sets the strip handle as the translator context. Later, in the _rmt_adapter() function, which is called by the translator, we get this descriptor using rmt_translator_get_context(), find out the contents of the "brightness" field and automatically apply it using scale8_video().
