Provided Methods§

Source

fn append_border( &self, outline: &RoundedRect, border_width: &[f32; 4], border_color: &[RGBA; 4], )

Appends a stroked border rectangle inside the given @outline.

The four sides of the border can have different widths and colors.

§outline

the outline of the border

§border_width

the stroke width of the border on the top, right, bottom and left side respectively.

§border_color

the color used on the top, right, bottom and left side.

Source

fn push_debug(&self, message: impl IntoGStr)

Inserts a debug node with a message.

Debug nodes don’t affect the rendering at all, but can be helpful in identifying parts of a render node tree dump, for example in the GTK inspector.

§message

a printf-style format string

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.
