Trait Implementations

impl AsMut<StructureRef> for VideoConverterConfig

fn as_mut(&mut self) -> &mut StructureRef

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<StructureRef> for VideoConverterConfig

fn as_ref(&self) -> &StructureRef

Converts this type into a shared reference of the (usually inferred) input type.
