Struct UpdateTextInput 

pub struct UpdateTextInput {
    pub node_id: WidgetId,
    pub new_text: String,
    pub new_caret: usize,
    pub new_anchor: usize,
    pub old_value: TextEditingValue,
    pub new_value: TextEditingValue,
    pub source: TextEditSource,
    pub phase: TextEditPhase,
    pub editing_action: Option<TextInputAction>,
    pub validation_state: Option<TextFieldValidationState>,
    pub validation_message: Option<String>,
}

Structured details for a text-input edit.

Every TextInput binding receives this value through ActionInput::text_change, while the bound action payload continues to carry the application’s stable context.

Fields

node_id: WidgetId

The widget identity of the text input that changed.

new_text: String

The complete new text value.

new_caret: usize

Byte offset of the caret (insertion point).

new_anchor: usize

Byte offset of the selection anchor (equals new_caret when no selection is active).

old_value: TextEditingValue

Complete value before the transaction. Older shell boundaries may not know it and use an empty value until they adopt the complete-value API.

new_value: TextEditingValue

Complete value after the transaction.

source: TextEditSource

Origin of this edit.

phase: TextEditPhase

Lifecycle phase represented by this action.

editing_action: Option<TextInputAction>

Configured software-keyboard action for submit/completion events.

validation_state: Option<TextFieldValidationState>

Validation state when phase is TextEditPhase::Validated.

validation_message: Option<String>

Accessible validation detail associated with validation_state.
