Structs

• ConditionalImageConfig
  Represents a conditional image element on a display.
• DisplayConfig
  Represents the display config. It holds the resolution and the elements to be rendered.
• ElementConfig
  Represents a single element to be rendered on a display.
• GraphConfig
  Represents a graph element on a display.
• ImageConfig
  Represents a static image element on a display.
• PrepareConditionalImageData
  Represents the preparation data for the render process. It holds all static assets to be rendered. This is done once before the loop starts. Each asset will be stored on the display locally, and load during the render process by its asset id / element id
• PrepareStaticImageData
  Represents the preparation data for the render process. It holds all static assets to be rendered. This is done once before the loop starts. Each asset will be stored on the display locally, and load during the render process by its asset id / element id
• PrepareTextData
  Represents the preparation data for the render process. It holds all static assets to be rendered. This is done once before the loop starts. Each asset will be stored on the display locally, and load during the render process by its asset id / element id
• RenderData
  Represents the data to be rendered on a display. It holds the display config and the sensor values.
• SensorValue
  Provides a single SensorValue
• TextConfig
  Represents a text element on a display.
• TransportMessage
  Indicates the current type of message to be sent to the display. Either a message to prepares static assets, by sending them to the display, and then be stored on the fs. Or the actual render loop, where the prev. stored asses will be used to render the image. The type is used to deserialize the data to the correct struct. The data is a vector of bytes, which will be deserialized to the correct struct, depending on the type.

Enums

• ElementType
  Represents the type of an element on a display.
• GraphType
  Represents the type of a graph element on a display.
• SensorType
  Represents the type of a sensor value. This is used to determine how to render the value. For example a text value will be rendered as text, while a number value can be rendered as a graph.
• SensorValueModifier
  Represents the modifier of a sensor value. This is used to modify the value before rendering. For example to output the average or max value of a sensor.
• TextAlign
  Represents the text alignment of a text element.
• TransportType
  Represents the type of the message to be sent to the display. Either a message to prepares static assets, by sending them to the display, and then be stored on the fs. Or the actual render loop, where the prev. stored asses will be used to render the image. The type is used to deserialize the data to the correct struct.

Functions
