Enum ValidationError 

pub enum ValidationError {
    SmTooLow {
        required: u32,
        actual: u32,
        feature: String,
    },
    MmaSyncBf16Rejected {
        operand: &'static str,
    },
    LdMatrixBadRegType {
        operand: &'static str,
        found: PtxType,
    },
}

Errors returned by PtxModule::validate.

Scope is intentionally narrow — target-capability checks only, no semantic analysis.

Variants

SmTooLow

A feature used by the module requires a higher SM target than the module declares.

Example: a kernel containing mma.sync.m16n8k16 in a module with .target sm_70 would yield required: 80, actual: 70, feature: "mma.sync.m16n8k16".

Fields

required: u32

Minimum SM version required by the offending feature.

actual: u32

SM version parsed from the module’s target string.

feature: String

Human-readable name of the offending feature.

MmaSyncBf16Rejected

A TensorCoreOp::MmaSync instruction was constructed with PtxType::BF16 on a_ty or b_ty. Bf16 emission must use the dedicated TensorCoreOp::MmaSyncBf16 variant so fragment types and instruction dtype stay aligned at the IR boundary.

Introduced in Sprint 9.1 cleanup; closes the legacy hole where the generic MmaSync path silently emitted a bf16 instruction from FragmentA_F16 / FragmentB_F16 operands.

Fields

operand: &'static str

Which operand carried the rejected dtype tag ("a_ty" or "b_ty").

LdMatrixBadRegType

A TensorCoreOp::LdMatrix instruction carries a register whose declared type is not PtxType::U32 (.b32 class). The mma variants get this for free from their typed fragment wrappers; LdMatrix takes raw registers, so the check lives here.

Destination registers hold packed 16-bit pairs (alloc_packed_half2 convention) and the address register is a shared-space .u32 byte address. Introduced in Sprint 9.3.

Fields

operand: &'static str

Which operand carried the rejected register ("dst" or "addr").

found: PtxType

The register’s declared PTX type.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Eq for ValidationError

impl Error for ValidationError

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.

impl PartialEq for ValidationError

fn eq(&self, other: &ValidationError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
