Trait PlatformAsyncDataTransferImpl 

pub trait PlatformAsyncDataTransferImpl {
    // Required methods
    fn provide_formats(&self) -> Result<Vec<DataFormat>, ClipboardError>;
    fn provide_items(
        &self,
    ) -> Result<Vec<Rc<dyn IAsyncDataTransferItem>>, ClipboardError>;
    fn dispose(&self, owner: &PlatformAsyncDataTransfer);
}

The members a platform backend provides for a PlatformAsyncDataTransfer.

Required Methods

fn provide_formats(&self) -> Result<Vec<DataFormat>, ClipboardError>

Provides the formats supported by the data transfer. Called until it succeeds: a failure is reported to the caller and not kept.

fn provide_items( &self, ) -> Result<Vec<Rc<dyn IAsyncDataTransferItem>>, ClipboardError>

Provides the items of the data transfer. Called until it succeeds: a failure is reported to the caller and not kept.

fn dispose(&self, owner: &PlatformAsyncDataTransfer)

Releases the platform resources of the data transfer. owner tells whether the formats and the items have been provided.

Dyn Compatibility

This trait is dyn compatible.

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