Struct ReflectAddAssign 

pub struct ReflectAddAssign {
    pub add_assign: fn(&mut dyn Reflect, Box<dyn PartialReflect>) -> Result<(), Option<Box<dyn PartialReflect>>>,
}

A struct used to perform addition assignment on reflected values.

A ReflectAddAssign for type T can be obtained via FromType::from_type.

Fields

add_assign: fn(&mut dyn Reflect, Box<dyn PartialReflect>) -> Result<(), Option<Box<dyn PartialReflect>>>

Function pointer implementing ReflectAddAssign::add_assign().

Implementations

impl ReflectAddAssign

pub fn add_assign( &self, a: &mut dyn Reflect, b: Box<dyn PartialReflect>, ) -> Result<(), Option<Box<dyn PartialReflect>>>

Adds a reflected value to another reflected value in place.

Errors

• Returns Err(None) if the first argument is of an incompatible type.
• Returns Err(Some(b)) if the second argument is of an incompatible type.

Trait Implementations

impl Clone for ReflectAddAssign

fn clone(&self) -> ReflectAddAssign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Reflect + AddAssign> FromType<T> for ReflectAddAssign

fn from_type() -> Self

Creates an instance of Self for type T.

fn insert_dependencies(_type_registration: &mut TypeRegistration)

Inserts TypeData dependencies of this TypeData. This is especially useful for trait TypeData that has a supertrait (ex: A: B). When the TypeData for A is inserted, the B TypeData will also be inserted.
