Struct ShapeGuardFailure 

pub struct ShapeGuardFailure { /* private fields */ }

Error returned by a shape-guard metadata query.

The public ShapeGuardError remains the typed source. The private side channel is shared with the owning ShapeGuardContext so an external message-only AD callback can report the same typed source at the runtime boundary without changing the callback protocol.

Examples

use computegraph::types::{ValueKey, ValueRef};
use tenferro_ops::input_key::TensorInputKey;
use tenferro_ops::std_tensor_op::StdTensorOp;
use tenferro_ops::{ShapeGuardContext, ShapeGuardError};

let key = ValueKey::<StdTensorOp>::Input(TensorInputKey::User { id: 8 });
let value = ValueRef::External(key);
let mut ctx = ShapeGuardContext::default();
let failure = ctx.shape_of(&value).unwrap_err();
assert!(matches!(
    failure.typed_source(),
    ShapeGuardError::MissingMetadata { .. }
));

Implementations

impl ShapeGuardFailure

pub fn typed_source(&self) -> &ShapeGuardError

Return the original typed shape-guard failure.

pub fn into_typed_source(self) -> ShapeGuardError

Consume this boundary error and return its original typed failure.

Trait Implementations

impl Clone for ShapeGuardFailure

fn clone(&self) -> ShapeGuardFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeGuardFailure

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

Formats the value using the given formatter.

impl Display for ShapeGuardFailure

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

Formats the value using the given formatter.

impl Error for ShapeGuardFailure

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<ShapeGuardFailure> for ADRuleError

Available on crate feature autodiff only.

fn from(err: ShapeGuardFailure) -> Self

Converts to this type from the input type.

impl PartialEq for ShapeGuardFailure

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