Enum PositionError 

pub enum PositionError {
    HeadDimMustBeEven {
        head_dim: usize,
    },
    SeqOffsetOutOfRange {
        offset: usize,
        max: usize,
    },
    ShapeMismatch {

}

Errors arising from position encoding operations.

Variants

HeadDimMustBeEven

head_dim must be even for RoPE.

Fields

head_dim: usize

SeqOffsetOutOfRange

Sequence offset exceeds the pre-computed cache.

Fields

offset: usize

max: usize

ShapeMismatch

Tensor shape mismatch.

Fields

expected: Vec<usize>

got: Vec<usize>

Trait Implementations

impl Clone for PositionError

fn clone(&self) -> PositionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PositionError

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

Formats the value using the given formatter.

impl Display for PositionError

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

Formats the value using the given formatter.

impl Error for PositionError

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<PositionError> for CachedAttentionError

fn from(e: PositionError) -> Self

Converts to this type from the input type.
