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

extract_value_sequence
