Enum HAlign 

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

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.
