    pub infinitely_growable: bool,
}

Internal sizing information for a single grid track (row/column) Gutters between tracks are sized similarly to actual tracks, so they are also represented by this struct

Fields

kind: GridTrackKind

Whether the track is a full track, a gutter, or a placeholder that has not yet been initialised

is_collapsed: bool

Whether the track is a collapsed track/gutter. Collapsed tracks are effectively treated as if they don’t exist for the purposes of grid sizing. Gutters between collapsed tracks are also collapsed.

min_track_sizing_function: MinTrackSizingFunction

The minimum track sizing function of the track

max_track_sizing_function: MaxTrackSizingFunction

The maximum track sizing function of the track

offset: f32

The distance of the start of the track from the start of the grid container

base_size: f32

The size (width/height as applicable) of the track

growth_limit: f32

A temporary scratch value when sizing tracks Note: can be infinity

content_alignment_adjustment: f32

A temporary scratch value when sizing tracks. Is used as an additional amount to add to the estimate for the available space in the opposite axis when content sizing items

item_incurred_increase: f32

A temporary scratch value when “distributing space” to avoid clobbering planned increase variable

base_size_planned_increase: f32

A temporary scratch value when “distributing space” to avoid clobbering the main variable

growth_limit_planned_increase: f32

A temporary scratch value when “distributing space” to avoid clobbering the main variable

infinitely_growable: bool

A temporary scratch value when “distributing space” See: https://www.w3.org/TR/css3-grid-layout/#infinitely-growable

Implementations

impl GridTrack

fn new_with_kind( kind: GridTrackKind, min_track_sizing_function: MinTrackSizingFunction, max_track_sizing_function: MaxTrackSizingFunction, ) -> GridTrack

GridTrack constructor with all configuration parameters for the other constructors exposed

pub fn new( min_track_sizing_function: MinTrackSizingFunction, max_track_sizing_function: MaxTrackSizingFunction, ) -> GridTrack

Create new GridTrack representing an actual track (not a gutter)

pub fn gutter(size: LengthPercentage) -> GridTrack

Create a new GridTrack representing a gutter

pub fn collapse(&mut self)

Mark a GridTrack as collapsed. Also sets both of the track’s sizing functions to fixed zero-sized sizing functions.

pub fn is_flexible(&self) -> bool

Returns true if the track is flexible (has a Flex MaxTrackSizingFunction), else false.

pub fn uses_percentage(&self) -> bool

Returns true if the track is flexible (has a Flex MaxTrackSizingFunction), else false.

pub fn has_intrinsic_sizing_function(&self) -> bool

Returns true if the track has an intrinsic min and or max sizing function

pub fn fit_content_limit(&self, axis_available_grid_space: Option<f32>) -> f32

Returns true if the track is flexible (has a Flex MaxTrackSizingFunction), else false.

pub fn fit_content_limited_growth_limit( &self, axis_available_grid_space: Option<f32>, ) -> f32

Returns true if the track is flexible (has a Flex MaxTrackSizingFunction), else false.

pub fn flex_factor(&self) -> f32

Returns the track’s flex factor if it is a flex track, else 0.

Trait Implementations
