Fieldsยง

ยงunsafety: bool
๐Ÿ”ฌThis is a nightly-only experimental API. (type_info)

Unsafety, true is unsafe

๐Ÿ”ฌThis is a nightly-only experimental API. (type_info)

Abi, e.g. extern โ€œCโ€

ยงinputs: &'static [TypeId]
๐Ÿ”ฌThis is a nightly-only experimental API. (type_info)

Function inputs

ยงoutput: TypeId
๐Ÿ”ฌThis is a nightly-only experimental API. (type_info)

Function return type, default is TypeId::of::<()>

ยงvariadic: bool
๐Ÿ”ฌThis is a nightly-only experimental API. (type_info)

Vardiadic function, e.g. extern โ€œCโ€ fn add(n: usize, mut args: โ€ฆ);

where T: Any,

Sourceยง

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

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Sourceยง

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Anyโ€™s vtable from &Traitโ€™s.
Sourceยง

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Anyโ€™s vtable from &mut Traitโ€™s.
