Struct ComponentArguments

pub struct ComponentArguments {
    pub args: Vec<(String, String)>,
    pub accepts_text: bool,
}

A component can take various arguments (to pass down to its children), which are then later compiled into Rust function arguments - for example

<component name="test" args="a: String, b: bool, c: HashMap<X, Y>">
    <Button id="my_button" class="test_{{ a }}"> Is this true? Scientists say: {{ b }}</Button>
</component>

… will turn into the following (generated) Rust code:

struct TestRendererArgs<'a> {
    a: &'a String,
    b: &'a bool,
    c: &'a HashMap<X, Y>,
}

fn render_component_test<'a, T>(args: &TestRendererArgs<'a>) -> StyledDom {
    Button::with_label(format!("Is this true? Scientists say: {:?}", args.b)).with_class(format!("test_{}", args.a))
}

For this to work, a component has to note all its arguments and types that it can take. If a type is not str or String, it will be formatted using the {:?} formatter in the generated source code, otherwise the compiler will use the {} formatter.

Fields

args: Vec<(String, String)>

The arguments of the component, i.e. date => String

accepts_text: bool

Whether this widget accepts text. Note that this will be passed as the first argument when rendering the Rust code.

Trait Implementations

impl Clone for ComponentArguments

fn clone(&self) -> ComponentArguments

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentArguments

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

Formats the value using the given formatter.

impl Default for ComponentArguments

fn default() -> ComponentArguments

Returns the “default value” for a type.

impl Hash for ComponentArguments

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 Ord for ComponentArguments

fn cmp(&self, other: &ComponentArguments) -> 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,

Restrict a value to a certain interval.

impl PartialEq for ComponentArguments

fn eq(&self, other: &ComponentArguments) -> 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 PartialOrd for ComponentArguments

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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