Methods from Deref<Target = MessageArguments>

pub fn as_ptr(&self) -> *mut MessageArgumentsWrapper

pub fn get_source(&self) -> Result<Option<Weak<Node>>, Error>

Returns the source node for a message.

pub fn set_handled(&self, handled: bool) -> Result<(), Error>

Sets the handling status for a message.

pub fn is_handled(&self) -> Result<bool, Error>

Returns whether the message is handled.

where T: PropertyTypeConstraint,

Returns the value of an argument.

Returns

The value of the argument. If the argument is not present in this message arguments instance, returns the default value of the PropertyType.

pub fn get_optional_argument<T>( &self, property: &PropertyType<T>, ) -> Result<Option<<T as VariantConstraint>::RetArg>, Error>

where T: PropertyTypeConstraint,

Returns the value of an argument.

Returns

The value of the argument. If the argument is not present in this message arguments instance, returns None.

pub fn set_argument<T>( &self, property: &PropertyType<T>, value: <T as VariantConstraint>::DataArg<'_>, ) -> Result<(), Error>

where T: PropertyTypeConstraint,

Sets the value of an argument.
