Struct PropertyAttributeWhen 

#[non_exhaustive]
pub struct PropertyAttributeWhen {
    pub data: Arc<dyn Any + Send + Sync>,
    pub default: Option<Arc<dyn Fn() -> Vec<Box<dyn AnyPropertyAttribute>> + Send + Sync>>,
}

Data for a property attribute associated with an WhenInfo.

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.

data: Arc<dyn Any + Send + Sync>

Data for all inputs.

default: Option<Arc<dyn Fn() -> Vec<Box<dyn AnyPropertyAttribute>> + Send + Sync>>

Closure that generates the default attribute actions, used when the final widget has no attribute instance.

The closure must generate an action that behaves like the attribute is not present and then activates when the condition data activates.

If the final widget has no action and all when data for it has no default, the data is ignored.

Implementations

impl PropertyAttributeWhen

pub fn new<D, F>(data: D, default_action: F) -> Self

where D: Any + Send + Sync + 'static, F: Fn() -> Vec<Box<dyn AnyPropertyAttribute>> + Send + Sync + 'static,

New from strongly typed values.

pub fn new_no_default(data: impl Any + Send + Sync + 'static) -> Self

New from data, is only used if the action is provided by another data or the widget builder.

Trait Implementations

impl Clone for PropertyAttributeWhen

fn clone(&self) -> PropertyAttributeWhen

Returns a duplicate of the value.

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

Performs copy-assignment from source.
