fn src_activate( self, pad: &Pad, _imp: &Self::ElementImpl, ) -> Result<(), LoggableError>

fn src_activatemode( self, _pad: &Pad, _imp: &Self::ElementImpl, _mode: PadMode, _active: bool, ) -> Result<(), LoggableError>

fn src_event(self, pad: &Pad, imp: &Self::ElementImpl, event: Event) -> bool

fn src_event_full( self, pad: &Pad, imp: &Self::ElementImpl, event: Event, ) -> Result<FlowSuccess, FlowError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
