Struct Semantics 

pub struct Semantics {
    pub role: String,
    pub label: Option<String>,
    pub presents: Option<String>,
    pub attaches: bool,
    pub not_in_gallery: Option<String>,
}

How assistive technology and tests see a component.

Fields

role: String

The accessibility role, as accesskit names it.

label: Option<String>

The prop that names the component to assistive technology, when one does.

presents: Option<String>

The prop holding the resource the component presents, when it presents one.

attaches: bool

The component draws nothing where it stands: it gives the view it stands in something to do (a context menu, a toolbar on hover, a swipe). Wherever a view’s body puts it, it belongs to that view; a list item holds those of its row.

not_in_gallery: Option<String>

Why the gallery cannot show it, when it cannot (#[component(not_in_gallery = "…")] at the component’s declaration): a component that only means something in a live session — a place’s window well, which draws nothing and holds the app’s own window — is left out of the gallery by its own declaration, never by a name list in a check. None when the gallery can show it.

Trait Implementations

impl Clone for Semantics

fn clone(&self) -> Semantics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Semantics

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

Formats the value using the given formatter.

impl Default for Semantics

fn default() -> Semantics

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Semantics

fn deserialize<__D>( __deserializer: __D, ) -> Result<Semantics, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Semantics

fn eq(&self, other: &Semantics) -> 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 Serialize for Semantics

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
