Enum Align 

#[non_exhaustive]
pub enum Align {
    Left,
    Center,
    Right,
}

Horizontal alignment of one line of text within the columns it’s rendered into.

A builder knob on the single-line text widgets (Text, PrintLine) and on the titles of Panel and Modal. Text widgets default to Left (their long-standing behavior); panel/modal titles default to Center (theirs).

A plain re-export of retroglyph_core::layout::HAlign, not a separate type: core::align needs nothing from the egc feature, so there’s no reason for widgets to keep its own copy of the enum or of offset’s formula. Interoperates directly with Surface::print_aligned and TextLayout, no conversion needed. Horizontal alignment within a bounded rectangle.

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.

Left

Align text to the left edge (default).

Center

Centre text horizontally.

Right

Align text to the right edge.

Implementations

impl HAlign

pub const fn offset(self, area_width: u16, content_width: u16) -> u16

The left offset, in columns, at which a content_width-column line should start within an area_width-column area for this alignment.

Saturates at 0 when the content is wider than the area, so the caller clips from the left edge rather than underflowing.
