Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

No border.

Single

A single line box.

Double

A double line box.

Rounded

Like Single, but with rounded corners (, etc).

Solid

Adds a single whitespace cell of padding.

Shadow

A drop shadow effect by blending with the background.

Uniform(WindowBorderChar)

A single character used for the whole border:

aaaaa a a a a aaaaa

CornersEdges(WindowBorderCharWindowBorderChar)

A tuple (a, b) where a is used for the border’s corners and b for its edges:

abbba b b b b abbba

CornersHorizontalVertical(WindowBorderCharWindowBorderCharWindowBorderCharWindowBorderChar)

A tuple (a, b, c, d) where a and c are used for the border’s corners, b for its horizontal edges and d for the vertical ones:

abbbc d d d d cbbba

Anal(WindowBorderCharWindowBorderCharWindowBorderCharWindowBorderCharWindowBorderCharWindowBorderCharWindowBorderCharWindowBorderChar)

Use this if you’re a control freak and want to specify every single corner and edge character individually. The tuple (a, b, c, d, e, f, g, h) specifies every corner and edge character clockwise:

abbbc h d h d gfffe
