Struct PreparedOperationPlan 

pub struct PreparedOperationPlan { /* private fields */ }

Runtime-owned prepared operation plan with separated metadata and optional execution bridge.

Core operations are metadata-only because scheduled execution dispatches them through the selected engine’s core executor. Extension operations carry an executor bridge that is invoked only by the scheduled runtime loop.

Examples

use std::fmt::Debug;
use tenferro_runtime::PreparedOperationPlan;

fn requires_debug<T: Debug>() {}
requires_debug::<PreparedOperationPlan>();

Implementations

impl PreparedOperationPlan

pub fn metadata(operation: PreparedOperationHandle) -> Self

Construct a metadata-only prepared operation plan.

Examples

use tenferro_runtime::{PreparedOperationHandle, PreparedOperationPlan};

fn provider_handle() -> PreparedOperationHandle {
    unreachable!("example is type-checked but not executed")
}

if false {
    let plan = PreparedOperationPlan::metadata(provider_handle());
    assert!(plan.executor().is_none());
}

pub fn executable( operation: PreparedOperationHandle, executor: PreparedOperationExecutorHandle, ) -> Self

Construct an executable prepared operation plan.

Examples

use tenferro_runtime::{
    PreparedOperationExecutorHandle, PreparedOperationHandle, PreparedOperationPlan,
};

fn provider_handle() -> PreparedOperationHandle {
    unreachable!("example is type-checked but not executed")
}

fn executor_handle() -> PreparedOperationExecutorHandle {
    unreachable!("example is type-checked but not executed")
}

if false {
    let plan = PreparedOperationPlan::executable(provider_handle(), executor_handle());
    assert!(plan.executor().is_some());
}

pub fn operation(&self) -> &PreparedOperationHandle

Return the prepared-operation metadata handle.

Examples

use tenferro_runtime::{PreparedOperationHandle, PreparedOperationPlan};

fn provider_handle() -> PreparedOperationHandle {
    unreachable!("example is type-checked but not executed")
}

if false {
    let plan = PreparedOperationPlan::metadata(provider_handle());
    let _operation = plan.operation();
}

pub fn binding(&self) -> &PreparedOperationBinding

Return the runtime-created binding carried by the metadata operation.

Examples

use tenferro_runtime::{PreparedOperationHandle, PreparedOperationPlan};

fn provider_handle() -> PreparedOperationHandle {
    unreachable!("example is type-checked but not executed")
}

if false {
    let plan = PreparedOperationPlan::metadata(provider_handle());
    let _binding = plan.binding();
}

pub fn specialization(&self) -> &SpecializationProjection

Return the specialization projection carried by the metadata operation.

Examples

use tenferro_runtime::{PreparedOperationHandle, PreparedOperationPlan};

fn provider_handle() -> PreparedOperationHandle {
    unreachable!("example is type-checked but not executed")
}

if false {
    let plan = PreparedOperationPlan::metadata(provider_handle());
    let _specialization = plan.specialization();
}

pub fn retained_bytes(&self) -> usize

Return logical heap bytes owned by metadata and executor handles.

Examples

use tenferro_runtime::{PreparedOperationHandle, PreparedOperationPlan};

fn provider_handle() -> PreparedOperationHandle {
    unreachable!("example is type-checked but not executed")
}

if false {
    let plan = PreparedOperationPlan::metadata(provider_handle());
    let _bytes = plan.retained_bytes();
}
