Struct States 

pub struct States {
    pub disabled: bool,
    pub focused: bool,
    pub selected: bool,
    pub expanded: bool,
    pub required: bool,
    pub invalid: bool,
    pub hidden: bool,
    pub modal: bool,
    pub checked: Option<TriState>,
    pub busy: bool,
}

Node state flags.

Fields

disabled: bool

Disabled.

focused: bool

Focused (at most one per tree — audited).

selected: bool

Selected.

expanded: bool

Expanded (collapsible containers).

required: bool

Required (form input).

invalid: bool

Invalid (form input with an error).

hidden: bool

Hidden from the a11y tree (still present for focus management).

modal: bool

Modal (blocks sibling interaction).

checked: Option<TriState>

Checkbox value.

busy: bool

Busy: the value is transient or not yet settled.

Two callers need this and neither had a way to say it (found by composing input-kit against this crate, 2026-10-18):

• IME composition. A textbox whose value is a half-formed syllable must not have that value announced. aria-busy is the signal, and input-kit’s Composer::is_composing is what drives it.
• Async loading. A textbox whose value is still being fetched should not be announced as empty.

busy is distinct from disabled and invalid: the control is live and valid, only its value is not final.
