Enum IntoValueError 

pub enum IntoValueError<H> {
    NotUnique(H),
    Extract {
        value: H,
        error: GroupError,
    },
}

Error returned when a value cannot be consumed without changing its owner.

Examples

use tenferro_ad::{EagerRuntime, EagerTensor, IntoValueError, Tensor};
use tenferro_cpu::CpuBackend;

let ctx = EagerRuntime::with_cpu_backend(CpuBackend::new())?;
let value = EagerTensor::from_tensor_in(
    Tensor::from_vec_col_major(vec![1], vec![1.0_f64])?,
    ctx,
)?;
let _shared = value.clone();
assert!(matches!(
    value.into_value(),
    Err(IntoValueError::NotUnique(_))
));

Variants

NotUnique(H)

Another eager handle, tape record, or checkpoint retains the value.

Extract

Group extraction failed after the handle was uniquely acquired.

Fields

value: H

error: GroupError

Trait Implementations

impl<H: Debug> Debug for IntoValueError<H>

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

Formats the value using the given formatter.

impl<H> Display for IntoValueError<H>

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

Formats the value using the given formatter.

impl<H: Debug + Send + Sync + 'static> Error for IntoValueError<H>

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
