#[repr(C)]
pub struct FFI_PhysicalOptimizerRule {
    pub optimize: unsafe extern "C" fn(_: &Self, plan: &FFI_ExecutionPlan, config: FFI_ConfigOptions) -> FFI_Result<FFI_ExecutionPlan>,
    pub name: unsafe extern "C" fn(&Self) -> String,

}

A stable struct for sharing PhysicalOptimizerRule across FFI boundaries.

Fields

optimize: unsafe extern "C" fn(_: &Self, plan: &FFI_ExecutionPlan, config: FFI_ConfigOptions) -> FFI_Result<FFI_ExecutionPlan>

name: unsafe extern "C" fn(&Self) -> String

schema_check: unsafe extern "C" fn(&Self) -> bool

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

Used to create a clone on the rule. 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 rule.

private_data: *mut c_void

Internal data. This is only to be accessed by the provider of the rule. A ForeignPhysicalOptimizerRule 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_PhysicalOptimizerRule

pub fn new( rule: Arc<dyn PhysicalOptimizerRule + Send + Sync>, runtime: Option<Handle>, ) -> Self

Creates a new FFI_PhysicalOptimizerRule.

Trait Implementations

impl Clone for FFI_PhysicalOptimizerRule

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_PhysicalOptimizerRule

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

Formats the value using the given formatter.

impl Drop for FFI_PhysicalOptimizerRule

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_PhysicalOptimizerRule> for Arc<dyn PhysicalOptimizerRule + Send + Sync>

fn from(rule: &FFI_PhysicalOptimizerRule) -> Self

Converts to this type from the input type.

impl Send for FFI_PhysicalOptimizerRule

impl Sync for FFI_PhysicalOptimizerRule
