Struct DetailedGridTracksInfo

Information from the computation of grids tracks

Fields

negative_implicit_tracks: u16

Number of leading implicit grid tracks

explicit_tracks: u16

Number of explicit grid tracks

positive_implicit_tracks: u16

Number of trailing implicit grid tracks

positions: Vec<Line<f32>>

The start and end position of each track relative to the grid container’s border box. These positions account for the container’s border and padding, the gap property, content alignment (align-content/justify-content), and collapsed tracks.

collapsed_tracks: Vec<Range<usize>>

Sorted, disjoint ranges of collapsed auto-fit tracks (indices into positions), whose adjacent gutters overlap when resolving absolute grid-area edges. Empty (and never allocated) unless a track collapsed.

empty_axis_line: Option<f32>

The position of the axis’ single grid line relative to the grid container’s border box when the axis has no tracks (an empty grid still contains one grid line in each axis, positioned by content alignment). None when the axis has tracks.

line_names: GridLineNames<S>

The names of each explicit grid line. Stored line i (0-indexed) bounds the start of explicit track i; use DetailedGridTracksInfo::names_for_line or DetailedGridTracksInfo::iter_line_names for indices relative to the full grid (including implicit tracks). Empty if the grid has no named lines.

Implementations

impl<S: CheapCloneStr> DetailedGridTracksInfo<S>

fn resolve_absolute_grid_axis( &self, placement: Line<GridPlacement<S>>, areas: &HashMap<StrHasher<S>, AreaLines, RandomState>, axis: GridAreaAxis, padding_start: f32, padding_end: f32, is_reversed: bool, ) -> Line<f32>

Resolve an absolute placement in this axis to physical start and end coordinates

fn absolute_track_edge( &self, index: usize, is_start: bool, is_reversed: bool, ) -> f32

Resolve a track edge, excluding gutters that overlap across a collapsed track run.

impl<S: CheapCloneStr> DetailedGridTracksInfo<S>

fn positions_from_grid_track_layout( grid_tracks: &[GridTrack], ) -> (Vec<Line<f32>>, Vec<Range<usize>>)

Get the start and end position of each track relative to the grid container’s border box, along with the index ranges of any runs of collapsed auto-fit tracks

fn from_grid_tracks_and_track_count( track_count: TrackCounts, grid_tracks: Vec<GridTrack>, line_names: GridLineNames<S>, ) -> Self

Construct DetailedGridTracksInfo from TrackCounts and GridTracks

pub fn names_for_line(&self, line_index: usize) -> &[S]

The names of the grid line with the passed 0-indexed line index, where line i bounds the start of track i of the full grid (including implicit tracks). Returns an empty slice if the line has no names or the index is out of range.

pub fn iter_line_names(&self) -> GridLineNamesIter<'_, S>

Iterate over the name group (&[S]) of each grid line of the full grid (including implicit tracks) in line order, yielding empty groups for unnamed (implicit) lines. Yields nothing if the grid has no named lines.

pub fn write_track_list(&self, out: &mut impl Write, zoom: f32) -> Result

Write the used track sizes and line names of this axis to the passed writer in the resolved value format of the grid-template-rows/grid-template-columns properties (see https://www.w3.org/TR/css-grid-1/#resolved-track-list) Track sizes are divided by zoom (the container’s effective CSS zoom, or 1.0) to give unzoomed px.

pub fn to_track_list_string(&self, zoom: f32) -> String

Serialize the used track sizes and line names of this axis in the resolved value format of the grid-template-rows/grid-template-columns properties (see https://www.w3.org/TR/css-grid-1/#resolved-track-list) Track sizes are divided by zoom (the container’s effective CSS zoom, or 1.0) to give unzoomed px.
