[][src]Enum pango::Gravity

#[non_exhaustive]pub enum Gravity {
    // some variants omitted

The Gravity type represents the orientation of glyphs in a segment of text. This is useful when rendering vertical text layouts. In those situations, the layout is rotated using a non-identity PangoMatrix, and then glyph orientation is controlled using Gravity. Not every value in this enumeration makes sense for every usage of Gravity; for example, Gravity::Auto only can be passed to Context::set_base_gravity and can only be returned by Context::get_base_gravity.

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.

Glyphs stand upright (default)


Glyphs are rotated 90 degrees clockwise


Glyphs are upside-down


Glyphs are rotated 90 degrees counter-clockwise


Gravity is resolved from the context matrix
