Trait DataTransferSend 

pub trait DataTransferSend: DataTransfer + Send {
    // Required method
    fn data_for_type(&self, type_: &dyn TransferType) -> Option<SendData>;
}

Trait for sending data via a data transfer.

See ActiveEventLoop::start_drag for where this is used. To build an implementation of this trait dynamically in a cross-platform way, use DataTransferSendBuilder.

Required Methods

fn data_for_type(&self, type_: &dyn TransferType) -> Option<SendData>

Get the data for the specified type, or None if this value does not supply the given data type.

Implementations

impl dyn DataTransferSend + '_

pub fn cast_ref<T: DataTransferSend>(&self) -> Option<&T>

Downcast to the backend concrete type.

Returns None if the object was not from that backend.

pub fn cast_mut<T: DataTransferSend>(&mut self) -> Option<&mut T>

Mutable downcast to the backend concrete type.

Returns None if the object was not from that backend.

pub fn cast<T: DataTransferSend>(self: Box<Self>) -> Result<Box<T>, Box<Self>>

Owned downcast to the backend concrete type.

Returns Err with self if the object was not from that backend.

Dyn Compatibility

This trait is dyn compatible.

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