Struct GridLayout 

pub struct GridLayout { /* private fields */ }

Pixel geometry of a grid, derived from its columns and the font’s metrics.

Column edges and baselines are whole pixels, so text is positioned identically every frame and glyphs stay crisp. All sizes are physical pixels.

Implementations

impl GridLayout

pub fn new(columns: &[Column], rows: u32, glyphs: &mut GlyphMap) -> Self

Layout for rows data rows (plus a header) of columns, drawn with glyphs.

pub fn rows(&self) -> u32

Data rows (the header is extra).

pub fn column_count(&self) -> usize

Number of columns.

pub fn row_height(&self) -> u32

Row pitch in pixels.

pub fn padding(&self) -> u32

Margin around the grid in pixels.

pub fn gap(&self) -> u32

Space between columns in pixels.

pub fn char_width(&self) -> f32

Advance of the font’s 0: the unit column widths are given in.

pub fn width(&self) -> u32

Total grid width in pixels, padding included.

pub fn height(&self) -> u32

Total grid height in pixels: header plus data rows, padding included.

pub fn column_x(&self, index: usize) -> u32

Left edge of column index.

Panics

If index is not a column.

pub fn column_width(&self, index: usize) -> u32

Width of column index in pixels.

Panics

If index is not a column.

pub fn column_chars(&self, index: usize) -> u32

Width of column index in characters.

Panics

If index is not a column.

pub fn row_y(&self, row: u32) -> u32

Top edge of grid row row (0 is the header).

pub fn baseline_y(&self, row: u32) -> f32

Baseline of grid row row (0 is the header), a whole pixel.

pub fn max_instances(&self) -> usize

Instances needed for a full frame in the worst case: the header bar, and per row a stripe, a background per cell and a glyph per character of every column.

Trait Implementations

impl Clone for GridLayout

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GridLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GridLayout

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
