Trait VisualExtensions 

pub trait VisualExtensions {
    // Required method
    fn render_to_with_dpi(
        &self,
        destination: &mut dyn Write,
        dpi: f64,
    ) -> Result<()>;

    // Provided method
    fn render_to(&self, destination: &mut dyn Write) -> Result<()> { ... }
}

Extension methods of controls for DevTools.

Required Methods

fn render_to_with_dpi( &self, destination: &mut dyn Write, dpi: f64, ) -> Result<()>

Render control to the destination stream.

destination is the destination stream; dpi the dpi quality. An error is what writing the image to the stream fails with.

Provided Methods

fn render_to(&self, destination: &mut dyn Write) -> Result<()>

Render control to the destination stream, at 96 DPI.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
