#[non_exhaustive]
pub enum DisplayError { InvalidFormatError, BusWriteError, DCError, CSError, DataFormatNotImplemented, RSError, OutOfBoundsError, }
Expand description

A ubiquitous error type for all kinds of problems which could happen when communicating with a display

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

InvalidFormatError

Invalid data format selected for interface selected

§

BusWriteError

Unable to write to bus

§

DCError

Unable to assert or de-assert data/command switching signal

§

CSError

Unable to assert chip select signal

§

DataFormatNotImplemented

The requested DataFormat is not implemented by this display interface implementation

§

RSError

Unable to assert or de-assert reset signal

§

OutOfBoundsError

Attempted to write to a non-existing pixel outside the display’s bounds
