}

Errors raised during sparse attention mask generation or forward pass.

Variants

InvalidWindowSize(usize)

Window size must be strictly positive.

InvalidSequenceLength(usize)

Sequence length must be strictly positive.

InvalidGlobalIndices

One or more global token indices exceed the sequence length.

Fields

index: usize

seq_len: usize

DimensionMismatch

Query, key, or value tensors have incompatible shapes.

Fields

context: String

expected: usize

got: usize

NumericalInstability

A softmax row collapsed to zero mass after masking.

Fields

position: usize

Trait Implementations

impl Clone for SparseAttentionError

fn clone(&self) -> SparseAttentionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseAttentionError

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

Formats the value using the given formatter.

impl Display for SparseAttentionError

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

Formats the value using the given formatter.

impl Error for SparseAttentionError

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<SparseAttentionError> for TrustformerError

fn from(err: SparseAttentionError) -> Self

Converts to this type from the input type.

impl PartialEq for SparseAttentionError

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