Trait embedded_text::style::height_mode::HeightMode

pub trait HeightMode: Copy {
    pub fn apply<C, F, A, V, H>(text_box: &mut StyledTextBox<'_, C, F, A, V, H>)
    where
        C: PixelColor,
        F: Font + Copy,
        A: HorizontalTextAlignment,
        V: VerticalTextAlignment,
        H: HeightMode;
    pub fn calculate_displayed_row_range<F: Font>(
        cursor: &Cursor<F>
    ) -> Range<i32>;
}

Specifies how the TextBox's height is adjusted when it is turned into a StyledTextBox.

Required methods

pub fn apply<C, F, A, V, H>(text_box: &mut StyledTextBox<'_, C, F, A, V, H>) where
    C: PixelColor,
    F: Font + Copy,
    A: HorizontalTextAlignment,
    V: VerticalTextAlignment,
    H: HeightMode, 

Apply the height mode to the textbox

Note: This function is used by TextBox::into_styled and normally does not need to be called manually.

pub fn calculate_displayed_row_range<F: Font>(cursor: &Cursor<F>) -> Range<i32>

Calculate the range of rows of the current line that can be drawn.

If a line does not fully fit in the bounding box, some HeightMode options allow drawing partial lines. For a partial line, this function calculates, which rows of each character should be displayed.
