Struct webui::Classes

pub struct Classes { /* private fields */ }

A set of classes.

The preferred way of creating this is using the [classes!][yew::classes!] macro.

Implementations

impl Classes

pub fn new() -> Classes

Creates an empty set of classes. (Does not allocate.)

pub fn with_capacity(n: usize) -> Classes

Creates an empty set of classes with capacity for n elements. (Does not allocate if n is zero.)

pub fn push<T>(&mut self, class: T)where
    T: Into<Classes>,

Adds a class to a set.

If the provided class has already been added, this method will ignore it.

pub unsafe fn unchecked_push<T>(&mut self, class: T)where
    T: Into<Cow<'static, str>>,

Adds a class to a set.

If the provided class has already been added, this method will ignore it.

This method won’t check if there are multiple classes in the input string.

Safety

This function will not split the string into multiple classes. Please do not use it unless you are absolutely certain that the string does not contain any whitespace. Using push() is preferred.

pub fn contains<T>(&self, class: T) -> boolwhere
    T: AsRef<str>,

Check the set contains a class.

pub fn is_empty(&self) -> bool

Check the set is empty.

Trait Implementations

impl Clone for Classes

fn clone(&self) -> Classes

    T: Into<Classes>,

fn extend<I>(&mut self, iter: I)where
    I: IntoIterator<Item = T>,

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl From<&'static str> for Classes

fn from(t: &'static str) -> Classes

Converts to this type from the input type.

impl<T> From<&[T]> for Classeswhere
    T: Into<Classes> + Clone,

impl From<&String> for Classes

fn from(t: &String) -> Classes

Converts to this type from the input type.

impl From<Cow<'static, str>> for Classes

fn from(t: Cow<'static, str>) -> Classes

Converts to this type from the input type.

impl<T> From<Option<T>> for Classeswhere
    T: Into<Classes>,

fn from(t: Option<T>) -> Classes

Converts to this type from the input type.

impl From<String> for Classes

fn from(t: String) -> Classes

Converts to this type from the input type.

impl<T> From<Vec<T, Global>> for Classeswhere
    T: Into<Classes>,

fn from(t: Vec<T, Global>) -> Classes

Converts to this type from the input type.

impl<T> FromIterator<T> for Classeswhere
    T: Into<Classes>,

fn from_iter<IT>(iter: IT) -> Classeswhere
    IT: IntoIterator<Item = T>,

Creates a value from an iterator.

impl IntoIterator for Classes

type Item = Cow<'static, str>

The type of the elements being iterated over.

type IntoIter = IntoIter<Cow<'static, str>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <Classes as IntoIterator>::IntoIter

Creates an iterator from a value.

impl IntoPropValue<AttrValue> for Classes

fn into_prop_value(self) -> AttrValue

Convert self to a value of a Properties struct.

impl IntoPropValue<Classes> for &'static str

fn into_prop_value(self) -> Classes

Convert self to a value of a Properties struct.

impl IntoPropValue<Option<AttrValue>> for Classes

fn into_prop_value(self) -> Option<AttrValue>

Convert self to a value of a Properties struct.

impl PartialEq<Classes> for Classes

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

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

const 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 ToString for Classes

fn to_string(&self) -> String

Converts the given value to a String.
