Enum ShapeGuardError 

pub enum ShapeGuardError {
    LocalWithoutAttachedGraph {
        local_id: usize,
    },
    LocalOutOfBounds {
        local_id: usize,
    },

        key: ValueKey<StdTensorOp>,
    },
    NonExactShape {
        key: ValueKey<StdTensorOp>,
    },
}

Error returned when shape-guard metadata cannot be resolved.

Variants

LocalWithoutAttachedGraph

A local graph value was queried before a graph was attached.

Fields

local_id: usize

Graph-local value id.

LocalOutOfBounds

A local graph value id is outside the attached graph’s value table.

Fields

local_id: usize

Graph-local value id.

MissingMetadata

No metadata was registered for the resolved value key.

Fields

key: ValueKey<StdTensorOp>

Resolved value key.

NonExactShape

Metadata exists, but at least one axis is only bounded or unknown.

Fields

key: ValueKey<StdTensorOp>

Resolved value key.

Trait Implementations

impl Clone for ShapeGuardError

fn clone(&self) -> ShapeGuardError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeGuardError

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

Formats the value using the given formatter.

impl Display for ShapeGuardError

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

Formats the value using the given formatter.

impl Error for ShapeGuardError

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<ShapeGuardError> for ADRuleError

Available on crate feature autodiff only.

fn from(err: ShapeGuardError) -> Self

Converts to this type from the input type.

impl PartialEq for ShapeGuardError

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