Type Alias GridLine

pub(crate) type GridLine = GenericGridLine<i32>;

The computed value of a <grid-line>.

Aliased Type

struct GridLine {
    pub ident: CustomIdent,
    pub line_num: i32,
    pub is_span: bool,
}

Fields

ident: CustomIdent

A custom identifier for named lines, or the empty atom otherwise.

https://drafts.csswg.org/css-grid/#grid-placement-slot

line_num: i32

Denotes the nth grid line from grid item’s placement.

This is clamped by MIN_GRID_LINE and MAX_GRID_LINE.

NOTE(emilio): If we ever allow animating these we need to either do something more complicated for the clamping, or do this clamping at used-value time.

is_span: bool

Flag to check whether it’s a span keyword.

Implementations

impl<Integer> GenericGridLine<Integer>

where Integer: PartialEq + Zero,

pub fn auto() -> GenericGridLine<Integer>

The auto value.

pub fn is_auto(&self) -> bool

Check whether this <grid-line> represents an auto value.

pub fn is_ident_only(&self) -> bool

Check whether this <grid-line> represents a <custom-ident> value.

pub fn can_omit(&self, other: &GenericGridLine<Integer>) -> bool

Trait Implementations

impl<Integer> Clone for GenericGridLine<Integer>

where Integer: Clone,

fn clone(&self) -> GenericGridLine<Integer>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Integer> Debug for GenericGridLine<Integer>

where Integer: Debug,

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

Formats the value using the given formatter.

impl<Integer> Default for GenericGridLine<Integer>

where Integer: Default,

fn default() -> GenericGridLine<Integer>

Returns the “default value” for a type.

impl<Integer> MallocSizeOf for GenericGridLine<Integer>

where Integer: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<Integer> PartialEq for GenericGridLine<Integer>

where Integer: PartialEq,

fn eq(&self, other: &GenericGridLine<Integer>) -> 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.
