SemanticsSpec

Struct SemanticsSpec 

Source
pub struct SemanticsSpec {
    pub role: Option<Role>,
    pub label: Option<Arc<str>>,
    pub description: Option<Arc<str>>,
    pub value: Option<Arc<str>>,
    pub flags: SemanticsFlags,
}
Expand description

Especificación semántica completa de un nodo. Lo que el runtime traduce a un accesskit::Node cada frame.

label es lo que el lector enuncia primero (el “nombre accesible”). Si el nodo ya tiene un text visible y significativo, podés dejar label = None y el runtime usará ese texto como nombre — pero declararlo explícito es más robusto (e.g. un botón con sólo un ícono necesita label porque no hay texto visible).

value es el dato dinámico (texto del input, valor del slider). El lector suele leer label + value juntos: “Volumen, 70”.

description es contexto adicional (“Disminuye el volumen del sistema”). Los lectores lo leen tras una pausa o con un atajo distinto; usalo para info que ayude PERO no sobreloadées (los usuarios de TTS perciben ruido más que falta de info).

Implementations§

Source§

impl SemanticsSpec

Source

pub fn role(role: Role) -> Self

Especificación con sólo el rol fijado. Atajo común; los demás campos quedan None y los flags vacíos.

pub fn with_label(self, s: impl Into<Arc<str>>) -> Self

Pone label (consumiendo cualquier valor previo).

Source

pub fn with_description(self, s: impl Into<Arc<str>>) -> Self

Pone description.

Source

pub fn with_value(self, s: impl Into<Arc<str>>) -> Self

Pone value.

Source

pub fn with_checked(self, v: bool) -> Self

Pone flags.checked = Some(v).
