Struct OriginZeroLine

#[repr(transparent)]
pub struct OriginZeroLine(pub i16);

Represents a grid line position in “OriginZero” coordinates

“OriginZero” coordinates are a normalized form:

• The line at left hand (or top) edge of the explicit grid is line 0
• The next line to the right (or down) is 1, and so on
• The next line to the left (or up) is -1, and so on

Implementations

impl OriginZeroLine

pub(crate) fn into_track_vec_index(self, track_counts: TrackCounts) -> usize

Converts a grid line in OriginZero coordinates into the index of that same grid line in the GridTrackVec.

pub(crate) fn try_into_track_vec_index( self, track_counts: TrackCounts, ) -> Option<usize>

Converts a grid line in OriginZero coordinates into the index of that same grid line in the GridTrackVec.

This fallible version is used for the placement of absolutely positioned grid items:

If a grid-placement property refers to a non-existent line either by explicitly specifying such a line or by spanning outside of the existing implicit grid, it is instead treated as specifying auto (instead of creating new implicit grid lines).

The infallible version above if used when placing regular in-flow grid items.

pub(crate) fn implied_negative_implicit_tracks(self) -> u16

The minimum number of negative implicit track there must be if a grid item starts at this line.

pub(crate) fn implied_positive_implicit_tracks( self, explicit_track_count: u16, ) -> u16

The minimum number of positive implicit track there must be if a grid item end at this line.

Trait Implementations

impl Add<u16> for OriginZeroLine

type Output = OriginZeroLine

The resulting type after applying the + operator.

fn add(self, rhs: u16) -> Self::Output

Performs the + operation.

impl Add for OriginZeroLine

type Output = OriginZeroLine

The resulting type after applying the + operator.

fn add(self, rhs: OriginZeroLine) -> Self::Output

Performs the + operation.

impl AddAssign<u16> for OriginZeroLine

fn add_assign(&mut self, rhs: u16)

Performs the += operation.

impl Clone for OriginZeroLine

fn clone(&self) -> OriginZeroLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OriginZeroLine

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

Formats the value using the given formatter.

impl Ord for OriginZeroLine

fn cmp(&self, other: &OriginZeroLine) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for OriginZeroLine

fn eq(&self, other: &OriginZeroLine) -> 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.

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
