Struct FFI_PhysicalExtensionCodec 

pub struct FFI_PhysicalExtensionCodec {
    pub clone: unsafe extern "C" fn(plan: &Self) -> Self,
    pub release: unsafe extern "C" fn(arg: &mut Self),
    pub version: unsafe extern "C" fn() -> u64,
    pub private_data: *mut c_void,
    pub library_marker_id: extern "C" fn() -> usize,
    /* private fields */
}

A stable struct for sharing PhysicalExtensionCodec across FFI boundaries.

Fields

clone: unsafe extern "C" fn(plan: &Self) -> Self

Used to create a clone on the provider of the execution plan. This should only need to be called by the receiver of the plan.

release: unsafe extern "C" fn(arg: &mut Self)

Release the memory of the private data when it is no longer being used.

version: unsafe extern "C" fn() -> u64

Return the major DataFusion version number of this provider.

private_data: *mut c_void

Internal data. This is only to be accessed by the provider of the plan. A ForeignPhysicalExtensionCodec should never attempt to access this data.

library_marker_id: extern "C" fn() -> usize

Utility to identify when FFI objects are accessed locally through the foreign interface.

Implementations

impl FFI_PhysicalExtensionCodec

pub fn new( codec: Arc<dyn PhysicalExtensionCodec + Send>, runtime: Option<Handle>, task_ctx_provider: impl Into<FFI_TaskContextProvider>, ) -> Self

Creates a new FFI_PhysicalExtensionCodec.

Trait Implementations

impl Clone for FFI_PhysicalExtensionCodec

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FFI_PhysicalExtensionCodec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for FFI_PhysicalExtensionCodec

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl From<&FFI_PhysicalExtensionCodec> for Arc<dyn PhysicalExtensionCodec>

fn from(codec: &FFI_PhysicalExtensionCodec) -> Self

Converts to this type from the input type.

impl Send for FFI_PhysicalExtensionCodec

impl Sync for FFI_PhysicalExtensionCodec
