Module esp32_hal::prelude [−][src]
Expand description
The prelude.
To use the esp32_hal effectively, a lot 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 esp32_hal::prelude::*.

Exception handling
Structs
A spinlock and critical section section based mutex.
Traits
Trait for cancelable countdowns.
A count down timer
Any object implementing this trait guarantees exclusive access to the data contained within the mutex for the duration of the lock.
Marker trait that indicates that a timer is periodic

A count down timer
Feeds an existing watchdog to ensure the processor isn’t reset. Sometimes commonly referred to as “kicking” or “refreshing”.
Disables a running watchdog timer so the processor won’t be reset.
Enables A watchdog timer to reset the processor if software is frozen or stalled.
