Required Associated Constants

const NAME: &'static CStr

const ARGS: &'static CStr

const RETURN_TYPE: &'static CStr

Provided Associated Constants

const FILTER_MODE: FilterMode = FilterMode::Parallel

Required Associated Types

type Error: AsRef<CStr>

Filter error that can turned into a &CStr

type FrameType: Frame

type FilterData

Required Methods

fn create( input: MapRef<'_>, output: MapRef<'_>, data: Option<Box<Self::FilterData>>, core: CoreRef<'_>, ) -> Result<(), Self::Error>

Errors

Return Self::Error if anything happens during the filter creation. The error message will be passed to VapourSynth.

fn get_frame( &self, n: i32, activation_reason: VSActivationReason, frame_data: *mut *mut c_void, frame_ctx: FrameContext, core: CoreRef<'_>, ) -> Result<Option<Self::FrameType>, Self::Error>

Errors

Return Self::Error if anything happens during the filter creation. The error message will be passed to VapourSynth.

Provided Methods

fn free(self, core: CoreRef<'_>)

Free the filter

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.
