Struct ReflectSubAssign 

pub struct ReflectSubAssign {
    pub sub_assign: fn(&mut (dyn Reflect + 'static), Box<dyn PartialReflect>) -> Result<(), Option<Box<dyn PartialReflect>>>,
}

A struct used to perform subtraction assignment on reflected values.

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

Fields

sub_assign: fn(&mut (dyn Reflect + 'static), Box<dyn PartialReflect>) -> Result<(), Option<Box<dyn PartialReflect>>>

Function pointer implementing ReflectSubAssign::sub_assign().

Implementations

impl ReflectSubAssign

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

Subtracts a reflected value from 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 ReflectSubAssign

fn clone(&self) -> ReflectSubAssign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> FromType<T> for ReflectSubAssign

where T: Reflect + SubAssign,

fn from_type() -> ReflectSubAssign

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.
