Struct zng_app::widget::builder::NestPosition

pub struct NestPosition {
    pub group: NestGroup,
    pub index: u16,
}

Represents the sort index of a property or intrinsic node in a widget instance.

Each node “wraps” the next one, so the sort defines (context#0 (context#1 (event (size (border..))))).

Fields

group: NestGroup

The major position.

index: u16

Extra sorting within items of the same group.

Implementations

impl NestPosition

pub const INTRINSIC_INDEX: u16 = 21_845u16

Default index used for intrinsic nodes, is u16::MAX / 3.

pub const PROPERTY_INDEX: u16 = 43_690u16

Default index used for properties, is INTRINSIC_INDEX * 2.

pub fn property(group: NestGroup) -> Self

New position for property.

pub fn intrinsic(group: NestGroup) -> Self

New position for intrinsic node.

Trait Implementations

impl Clone for NestPosition

fn clone(&self) -> NestPosition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NestPosition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NestPosition

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for NestPosition

fn cmp(&self, other: &NestPosition) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for NestPosition

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for NestPosition

fn partial_cmp(&self, other: &NestPosition) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for NestPosition

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
