    },

    TrailingBytes {

}

Errors produced by SparseVector construction, encoding, and decoding.

Variants

LengthMismatch

indices and values had different lengths.

Fields

indices: usize

values: usize

UnsortedIndices

indices were not in strictly ascending order (which also forbids duplicates).

Fields

position: usize

prev: u32

curr: u32

NonFiniteWeight

A weight was non-finite (NaN or ±infinity).

Fields

position: usize

value: f32

Truncated

An encoded buffer was too short to contain its declared payload.

Fields

need: usize

got: usize

TrailingBytes

An encoded buffer carried trailing bytes after its declared payload.

Fields

trailing: usize

Trait Implementations

impl Clone for SparseError

fn clone(&self) -> SparseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseError

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

Formats the value using the given formatter.

impl Display for SparseError

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

Formats the value using the given formatter.

impl Error for SparseError

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 SparseError

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