Struct maomi::prop::BindingValue

pub struct BindingValue<T> { /* private fields */ }

A value that can be associated to a BindingProp .

Note that the BindingValue should be exclusively associated to one BindingProp . Panics if the value is associated to more than one BindingProp .

Implementations

impl<T> BindingValue<T>

pub fn new(default_value: T) -> Self

Create the property with initial value.

pub fn set(&mut self, v: T)

Set the value.

Updates of the value will NOT be applied to template! To change the value and apply in templates, create a new BindingValue instead.

pub fn with<R>(&self, f: impl FnOnce(&T) -> R) -> R

Get a reference of the value.

pub fn update<R>(&self, f: impl FnOnce(&mut T) -> R) -> R

Get a reference of the value.

Updates of the value will NOT be applied to template! To change the value and apply in templates, create a new BindingValue instead.

impl<T: Clone> BindingValue<T>

pub fn get(&self) -> T

Get the cloned value.

Trait Implementations

impl<T: Debug> Debug for BindingValue<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for BindingValue<T>

fn default() -> BindingValue<T>

Returns the “default value” for a type.

impl<T: Ord> Ord for BindingValue<T>

fn cmp(&self, other: &BindingValue<T>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq<BindingValue<T>> for BindingValue<T>

fn eq(&self, other: &BindingValue<T>) -> 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<T: PartialOrd> PartialOrd<BindingValue<T>> for BindingValue<T>

fn partial_cmp(&self, other: &BindingValue<T>) -> 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<T> PropertyUpdate<BindingValue<T>> for BindingProp<T>

type UpdateContext = bool

Must be bool if used in components and updated through templates.

fn compare_and_set_ref( dest: &mut Self, src: &BindingValue<T>, ctx: &mut Self::UpdateContext )

The updater.
