Implementations

impl dyn PieceXData

pub fn is<__T>(&self) -> bool

where __T: PieceXData,

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T>( self: Box<dyn PieceXData>, ) -> Result<Box<__T>, Box<dyn PieceXData>>

where __T: PieceXData,

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T>( self: Rc<dyn PieceXData>, ) -> Result<Rc<__T>, Rc<dyn PieceXData>>

where __T: PieceXData,

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T>(&self) -> Option<&__T>

where __T: PieceXData,

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>

where __T: PieceXData,

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.

Trait Implementations

Deserialize this value from the given Serde deserializer.

impl<'typetag> Serialize for dyn PieceXData + 'typetag

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<'typetag> Serialize for dyn PieceXData + Send + 'typetag

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

impl<'typetag> Serialize for dyn PieceXData + Send + Sync + 'typetag

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<'typetag> Serialize for dyn PieceXData + Sync + 'typetag

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
