Expand description

A core trait of bevy_reflect, used for downcasting to concrete types.

This is a subtrait of PartialReflect, meaning any type which implements Reflect implements PartialReflect by definition.

It’s recommended to use the derive macro rather than manually implementing this trait. Doing so will automatically implement this trait, PartialReflect, and many other useful traits for reflection, including one of the appropriate subtraits: Struct, TupleStruct or Enum.

If you need to use this trait as a generic bound along with other reflection traits, for your convenience, consider using Reflectable instead.

See the crate-level documentation to see how this trait can be used.

Required Methods§

Source

fn into_any(self: Box<Self>) -> Box<dyn Any>

Returns the value as a Box<dyn Any>.

For remote wrapper types, this will return the remote type instead.

Source

fn as_any(&self) -> &dyn Any

Returns the value as a &dyn Any.

For remote wrapper types, this will return the remote type instead.

Source

fn as_any_mut(&mut self) -> &mut dyn Any

Returns the value as a &mut dyn Any.

For remote wrapper types, this will return the remote type instead.

Source

fn into_reflect(self: Box<Self>) -> Box<dyn Reflect>

Casts this type to a boxed, fully-reflected value.

Source

fn as_reflect(&self) -> &dyn Reflect

Casts this type to a fully-reflected value.

Source

fn as_reflect_mut(&mut self) -> &mut dyn Reflect

Casts this type to a mutable, fully-reflected value.

Source

fn set(&mut self, value: Box<dyn Reflect>) -> Result<(), Box<dyn Reflect>>

Performs a type-checked assignment of a reflected value to this value.

If value does not contain a value of type T, returns an Err containing the trait object.
