Enum Strip 

#[non_exhaustive]
pub enum Strip {
    Across,
    Down,
}

Which way a Region::TabGroup’s strip runs.

Across is a row of tabs over the panes it opens; down is a column of them beside the panes. Both are the folder semantic, one pane showing at a time, and both put the strip first, so a tab is always read before the pane it opens.

Why the description says it

A renderer left to choose picks across every time, so a tab group that wants a column has no way to get one. Both shapes are in use: strips across a screen, and long settings panels with their sections listed down beside them. The language says both.

What is here and what is not

The direction, carried beside the region the way Showing is: this crate names the fact and the holder of the region states it, because the region member is a place and not a record of how it is dressed.

No default. A tab group that says nothing about its strip is the silence this type exists to end, so a holder has to pick one.

No breakpoint. Room is still the renderer’s to measure. A strip that runs down may fold over its panes when there is no room beside them, the way a row folds into a menu; what it may not do is run across when there is room, because then the description stopped being what was drawn.

Variants (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.

Across

A row over the panes.

Down

A column beside the panes.

Implementations

impl Strip

pub const fn runs_down(self) -> bool

Whether the tabs stack vertically.

What a renderer asks for the two things that turn on direction rather than on placement: the accessibility orientation a strip announces, and which pair of arrow keys moves between its tabs. A method for Region::name’s reason, so three renderers do not each write the comparison.
