Error type for StableHLO lowering and runtime PJRT plugin loading.

Examples

use tenferro_runtime::{DType, GraphCompiler, TracedTensor};
use tenferro_xla::{lower_compiled_to_stablehlo, Error};

let x = TracedTensor::input_symbolic_shape(DType::I64, 1).unwrap();
let mut compiler = GraphCompiler::new();
let y = x.neg().unwrap();
let program = compiler
    .compile_with_input_specs(&y, &[(&x, DType::I64, &[2])])
    .unwrap();
let err = lower_compiled_to_stablehlo(&program).unwrap_err();
assert!(matches!(err, Error::UnsupportedDType { .. }));

Implementations

impl Error

pub fn kind(&self) -> ErrorKind

Return the stable coarse classification for this XLA failure.

Examples

use tenferro_tensor::ErrorKind;
use tenferro_xla::Error;

assert_eq!(
    Error::UnsupportedOp { op: "Maximum", reason: "not lowered" }.kind(),
    ErrorKind::Unsupported,
);

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
