Trait DisplayDriver

pub trait DisplayDriver:

    + 'static {
    type Display: DrawTarget<Color = BinaryColor>;

    // Provided methods

Interface for display drivers.

TODO: Allow sync-only drivers?

Required Associated Types

type Display: DrawTarget<Color = BinaryColor>

Provided Methods

async fn init(&mut self) -> Result<(), DisplayError>

Called when the display is initialized.

It is guaranteed that:

• No other function is called before this function.
• If this function returns an error, other functions will not be called.

Default implementation returns Ok(()).

async fn flush(&mut self) -> Result<(), DisplayError>

async fn set_brightness(&mut self, _brightness: u8) -> Result<(), DisplayError>

Sets brightness of the display.

0 is off, 255 is full brightness.

async fn set_display_on(&mut self, on: bool) -> Result<(), DisplayError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
