Enum Error 

pub enum Error {
    NbitsUnsupported(usize),
    BucketCount {
        expected: usize,
        got: usize,
    },
    DimNotByteAligned {
        dim: usize,
        nbits: usize,
    },
    DimTooLarge(usize),
    Shape(String),
    LutMismatch,
}

Errors from building tables and queries or from shape validation.

Variants

NbitsUnsupported(usize)

nbits must be 1, 2, 4 or 8.

BucketCount

Expected 2^nbits bucket weights.

Fields

expected: usize

2^nbits.

got: usize

What was passed.

DimNotByteAligned

dim · nbits is not a multiple of 8, so rows would not be whole bytes.

Fields

dim: usize

The embedding dimension.

nbits: usize

The code width.

DimTooLarge(usize)

dim exceeds MAX_DIM.

Shape(String)

A slice length or stride does not match the declared shape.

LutMismatch

The query was prepared against a different table.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
