Enum UnresolvedMargin 

pub enum UnresolvedMargin {
    Zero,
    Auto,
    Length(PixelValue),
}

An unresolved CSS margin value.

Margins can be auto (for centering) or a length value that needs resolution against the containing block.

Variants

Zero

margin: 0 (default)

Auto

margin: auto (for centering, CSS 2.2 § 10.3.3)

Length(PixelValue)

A length value (px, %, em, vh, etc.)

Implementations

impl UnresolvedMargin

pub fn is_auto(&self) -> bool

Returns true if this is an auto margin

pub fn resolve(&self, ctx: &ResolutionContext) -> f32

Resolve this margin value to pixels.

• Auto returns 0.0 (actual auto margin calculation happens in layout)
• Zero returns 0.0
• Length is resolved using the resolution context

Trait Implementations

impl Clone for UnresolvedMargin

fn clone(&self) -> UnresolvedMargin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnresolvedMargin

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

Formats the value using the given formatter.

impl Default for UnresolvedMargin

fn default() -> UnresolvedMargin

Returns the “default value” for a type.

impl PartialEq for UnresolvedMargin

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