README
fission-semantics
Accessibility semantics for the Fission UI framework.
fission-semantics re-exports the semantic types defined in fission-ir -- Role, Semantics,
and ActionSet -- so that crates outside the core can depend on the accessibility vocabulary
without pulling in the full IR. These types describe what a node means to assistive technology
(screen readers, switch control) and to the event system (focusable, draggable, scrollable), as
opposed to how the node looks or where it is positioned.
Key types
Type | Description |
|---|---|
Role | Accessibility role enum: Button, Text, TextInput, Image, Checkbox, Switch, Dialog, Slider, Input, List, ListItem, Generic. |
Semantics | Full semantic metadata for a node -- role, label, value, focusability, drag-and-drop flags, scroll flags, toggle state, input mask, focus scope/barrier, and more. |
ActionSet | A collection of ActionEntry values that map ActionTrigger gestures (tap, drag, hover, focus, change, etc.) to action IDs dispatched by the event system. |
Usage example
use fission_semantics::{Role, Semantics, ActionSet};
let sem = Semantics {
role: Role::Button,
label: Some("Save".into()),
focusable: true,
..Semantics::default()
};
assert_eq!(sem.role, Role::Button);
assert!(!sem.disabled);
Status
Supported -- stable public API consumed by widgets, the accessibility bridge, and test tooling.
