Enum EngineExecutionContractError 

#[non_exhaustive]
pub enum EngineExecutionContractError {
    OutputResidencyMismatch {
        instruction_index: usize,
        output_slot: usize,
        engine_id: EngineId,
        storage_class: StorageClass,
        backend_family: Option<&'static str>,
        allocation_domain: Option<AllocationDomainId>,
    },
}

Reports a runtime execution bridge that violated its output contract.

Examples

use tenferro_runtime::{EngineExecutionContractError, EngineId, StorageClass};

let error = EngineExecutionContractError::OutputResidencyMismatch {
    instruction_index: 3,
    output_slot: 7,
    engine_id: EngineId::new("tenferro.cpu")?,
    storage_class: StorageClass::new("tenferro.storage.host")?,
    backend_family: Some("foreign-backend"),
    allocation_domain: None,
};
assert!(error.to_string().contains("output slot 7"));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OutputResidencyMismatch

An executor returned a tensor not owned by its scheduled engine/storage.

Fields

instruction_index: usize

Execution-program instruction that produced the invalid tensor.

output_slot: usize

Execution slot containing the invalid tensor.

engine_id: EngineId

Engine selected by the prepared schedule.

storage_class: StorageClass

Storage class selected by the prepared schedule.

backend_family: Option<&'static str>

Physical backend family reported by the tensor.

allocation_domain: Option<AllocationDomainId>

Physical allocation domain reported by the tensor.

Trait Implementations

impl Debug for EngineExecutionContractError

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

Formats the value using the given formatter.

impl Display for EngineExecutionContractError

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

Formats the value using the given formatter.

impl Error for EngineExecutionContractError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.
