Hera — Alpha v0.0.15

Introducing
Hera

A modern open-source application stack targeting Embedded Linux environments.

Get StartedDocumentation

main.rs

impl View for SomeComponent {
    fn build(&self, rt: &mut Runtime, env: &mut Environment) -> UiNode {
        h_stack()
          .child(spacer())
          .child(
            view(Color::rgba(0.2, 0.5, 0.9, 1.0))
              .frame(120.0, 40.0)
              .radius(self.radius)
              .shadow(Color::rgba(0.0, 0.0, 0.0, 0.2), 0.0, 4.0, 6.0))
          .child(spacer())
          .build(rt, env)
    }

Graphics

Vulkan Rendering

A performant, highly-optimized Vulkan renderer with support for modern graphics effects.

Security

Isolated Clients

Clients are un-priviledged and isolated from each other. Priviledged clients can compose the display.
