Typed contract violation in a tensor returned by a transfer provider.

Examples

use tenferro_runtime::{DType, TransferProviderContractError};

let error = TransferProviderContractError::DTypeMismatch {
    expected: DType::F64,
    actual: DType::F32,
};
assert!(error.to_string().contains("dtype"));

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.

LogicalElementCount

The logical source shape cannot be represented as an element count.

Fields

source: Error

Checked tensor shape-product failure.

DTypeMismatch

The returned tensor changed the source dtype.

Fields

expected: DType

Source dtype required by the request.

actual: DType

Dtype returned by the provider.

ShapeMismatch

The returned tensor changed the source shape.

Fields

expected: Vec<usize>

Source shape required by the request.

actual: Vec<usize>

Shape returned by the provider.

DestinationPlacementMismatch

The returned tensor placement is not accepted at the destination endpoint.

Fields

destination_engine_id: EngineId

Destination engine from the transfer request.

destination_storage_class: StorageClass

Destination storage class from the transfer request.

actual: Placement

Placement returned by the provider.

DestinationResidencyMismatch

The returned tensor has compatible metadata but is not owned by the destination engine’s backend or allocation domain.

Fields

destination_engine_id: EngineId

Destination engine from the transfer request.

destination_storage_class: StorageClass

Destination storage class from the transfer request.

actual_backend_family: Option<&'static str>

Physical backend family returned by the provider.

actual_allocation_domain: Option<AllocationDomainId>

Shared allocation domain returned by the provider.

InvalidBufferLength

The returned tensor’s buffer length does not match its shape.

Fields

expected: usize

Element count required by the returned shape.

actual: usize

Element count reported by the returned buffer.

Trait Implementations

impl Debug for TransferProviderContractError

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

Formats the value using the given formatter.

impl Display for TransferProviderContractError

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

Formats the value using the given formatter.

impl Error for TransferProviderContractError

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.
