Layout metrics snapshot.

A snapshot can be taken using the LayoutMetrics::snapshot.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

constraints: PxConstraints2d

The constraints.

inline_constraints: Option<InlineConstraints>

The inline_constraints.

z_constraints: PxConstraints

The z_constraints.

font_size: Px

The font_size.

root_font_size: Px

The root_font_size.

scale_factor: Factor

The scale_factor.

viewport: Size2D<Px, Px>

The viewport.

screen_density: PxDensity

The screen_density.

direction: LayoutDirection

The direction.

leftover: Size2D<Option<Px>, ()>

The leftover.

Implementations

impl LayoutMetricsSnapshot

pub fn masked_eq(&self, other: &LayoutMetricsSnapshot, mask: LayoutMask) -> bool

Gets if all of the fields in mask are equal between self and other.

Trait Implementations

impl Clone for LayoutMetricsSnapshot

fn clone(&self) -> LayoutMetricsSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutMetricsSnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LayoutMetricsSnapshot

fn deserialize<__D>( __deserializer: __D, ) -> Result<LayoutMetricsSnapshot, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for LayoutMetricsSnapshot

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LayoutMetricsSnapshot

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

impl Serialize for LayoutMetricsSnapshot

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
