Enum AbiError 

#[repr(i32)]
pub enum AbiError {
    NotAvailable = -1,
    InvalidPointer = -2,
    InvalidKernel = -3,
    MalformedPtx = -4,
    LaunchFailed = -5,
    QuotaExceeded = -6,
    Internal = -7,
    InvalidDimensions = -8,

    InvalidHandle = -11,
}

Negative i32 status codes returned by the wasi-cuda host functions.

These are stable across TensorWasm versions; client code may match on the numeric value if it needs to.

Variants

NotAvailable = -1

CUDA is not available on this host (no toolkit / no driver).

InvalidPointer = -2

A pointer / length pair pointed outside the caller’s linear memory.

InvalidKernel = -3

Wasi-cuda was passed a KernelId that is not registered (or that belongs to another instance).

MalformedPtx = -4

load_ptx was called with bytes that ptxas rejected.

LaunchFailed = -5

The CUDA driver returned an error during a launch / sync.

QuotaExceeded = -6

Resource limits (max kernels per instance, etc.) were exceeded.

Internal = -7

Generic internal error.

InvalidDimensions = -8

Launch grid / block dimensions exceeded hardware caps or were non-positive. Returned by the host before any CUDA driver call, allowing the guest to distinguish a launch-shape bug from a driver error.

InvalidArgs = -9

Caller passed a structurally invalid argument that is neither a memory-region issue nor a dimensions issue. Currently used for non-UTF8 entry names in load_ptx.

KernelArgsUnsupported = -10

Caller passed a well-formed, in-bounds kernel-argument buffer that exceeds the host’s sanity caps — total argv bytes greater than MAX_KERNEL_ARGS_BYTES (4 KiB) or more than MAX_KERNEL_ARGS (128) tagged records. Since v0.2.0 (W1.1) the typed-argv lane accepts arbitrary scalar + pointer argv below those caps; this code is reserved for cap busts and is kept distinct from AbiError::InvalidArgs so a guest can tell “your input shape is too big for the host to accept” from “your input bytes are malformed.” See wit/wasi-cuda.wit and crate::kernel_args::parse_argv for the contract.

InvalidHandle = -11

A device-memory handle (from alloc) was passed to free / memcpy-h2d / memcpy-d2h that is not registered, or that belongs to another instance. Mirrors AbiError::InvalidKernel for the kernel registry: a guest cannot forge another instance’s device buffer handle. See crate::device_mem::DeviceMemRegistry.

Implementations

impl AbiError

pub const fn code(self) -> i32

Convert to the wire i32 code.

pub fn name(self) -> &'static str

Stable, human-readable name (used for log fields).

Trait Implementations

impl Clone for AbiError

fn clone(&self) -> AbiError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AbiError

impl Debug for AbiError

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

Formats the value using the given formatter.

impl Eq for AbiError

impl From<BackPressureError> for AbiError

fn from(e: BackPressureError) -> Self

Converts to this type from the input type.

impl PartialEq for AbiError

fn eq(&self, other: &AbiError) -> 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.
