Module esp8266_hal::prelude

The prelude.

To use esp8266_hal effectively, a number of traits and types need to be imported. Instead of importing them one by one manually, the prelude contains the most commonly used imports that are used around application runtime management.

This can be imported as use esp8266_hal::prelude::*.
