Typed failure from a training-free quantizer or estimator.

Variants

EmptyVector

The input dimension is zero, for which a code direction is undefined.

DimensionTooLarge

The vector exceeds the dimension supported by the reused i8 kernel.

Fields

actual: usize

Supplied coordinate count.

maximum: usize

Largest accepted coordinate count.

NonFinite

A coordinate was NaN or infinite.

Fields

index: usize

Zero-based coordinate of the first rejected value.

NonUnitNorm

A caller-declared L2-normalized vector was outside the unit-norm band.

Fields

squared_norm_bits: u64

Computed squared L2 norm as IEEE binary64 bits.

tolerance_bits: u64

Absolute permitted deviation from one as IEEE binary64 bits.

OutputLength

A caller-owned output buffer had the wrong byte length.

Fields

expected: usize

Required byte count.

actual: usize

Supplied byte count.

CodeLength

A packed row had the wrong byte length for the query dimension.

Fields

expected: usize

Required byte count.

actual: usize

Supplied byte count.

NonZeroPadding

Unused low-order fields in a final partial byte were not zero.

Fields

byte: u8

Final byte containing non-canonical padding.

mask: u8

Mask selecting the unused low-order bits.

Trait Implementations

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
