Enum ActionData 

pub enum ActionData {
    Value(String),
    NumericValue(f64),
    ScrollAmount {
        direction: ScrollDirection,
        amount: f64,
    },
    TextSelection {
        start: u32,
        end: u32,
    },
}

Data associated with an action.

Variants

Value(String)

Text value for SetValue action

NumericValue(f64)

Numeric value for SetValue action

ScrollAmount

Scroll amount and direction

Fields

direction: ScrollDirection

amount: f64

TextSelection

Text selection range (character offsets, 0-based)

Fields

start: u32

end: u32

Implementations

impl ActionData

pub fn validate(&self, action: Action) -> Result<(), Error>

Validate that this ActionData has valid values for the given action.

Checks constraints that are always wrong regardless of element state:

• TextSelection: start must be ≤ end
• NumericValue: must be finite (not NaN or infinity)

Does NOT query the element (e.g., does not check if indices are within text length or if numeric value is within min/max range).

Trait Implementations

impl Clone for ActionData

fn clone(&self) -> ActionData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActionData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ActionData

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ActionData

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.
