Struct taffy::compute::grid::types::grid_track_counts::TrackCounts

pub(crate) struct TrackCounts {
    pub negative_implicit: u16,
    pub explicit: u16,
    pub positive_implicit: u16,
}

Stores the number of tracks in a given dimension. Stores separately the number of tracks in the implicit and explicit grids

Fields

negative_implicit: u16

The number of track in the implicit grid before the explicit grid

explicit: u16

The number of tracks in the explicit grid

positive_implicit: u16

The number of tracks in the implicit grid after the explicit grid

Implementations

impl TrackCounts

pub fn from_raw( negative_implicit: u16, explicit: u16, positive_implicit: u16, ) -> Self

Create a TrackCounts instance from raw track count numbers

pub fn len(&self) -> usize

Count the total number of tracks in the axis

pub fn implicit_start_line(&self) -> OriginZeroLine

The OriginZeroLine representing the start of the implicit grid

pub fn implicit_end_line(&self) -> OriginZeroLine

The OriginZeroLine representing the end of the implicit grid

impl TrackCounts

Conversion functions between OriginZero coordinates and CellOccupancyMatrix track indexes

pub fn oz_line_to_next_track(&self, index: OriginZeroLine) -> i16

Converts a grid line in OriginZero coordinates into the track immediately following that grid line as an index into the CellOccupancyMatrix.

pub fn oz_line_range_to_track_range( &self, input: Line<OriginZeroLine>, ) -> Range<i16>

Converts start and end grid lines in OriginZero coordinates into a range of tracks as indexes into the CellOccupancyMatrix

pub fn track_to_prev_oz_line(&self, index: u16) -> OriginZeroLine

Converts a track as an index into the CellOccupancyMatrix into the grid line immediately preceding that track in OriginZero coordinates.

pub fn track_range_to_oz_line_range( &self, input: Range<i16>, ) -> Line<OriginZeroLine>

Converts a range of tracks as indexes into the CellOccupancyMatrix into start and end grid lines in OriginZero coordinates

Trait Implementations

impl Clone for TrackCounts

fn clone(&self) -> TrackCounts

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TrackCounts

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

Formats the value using the given formatter.

impl Default for TrackCounts

fn default() -> TrackCounts

Returns the “default value” for a type.

impl PartialEq for TrackCounts

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
