Why a stored block was refused. Every variant is a refusal to guess.

Variants

Unmarked

The block carries no signature. Not treated as “probably fine”: an unmarked block was written by something whose layout is unknown, which is precisely the case that must not be trusted.

EmptyPayload

A block with no layers describes nothing and can vouch for nothing.

DegenerateLayer

A layer with no heads or zero head dimension.

Fields

layer: usize

n_kv_heads: usize

head_dim: usize

RaggedPayload

The payload does not agree with itself: layers of different shapes or lengths, or a layer whose buffers contradict its own seq_len.

Fields

layer: usize

field: &'static str

expected: String

found: String

PayloadMismatch

The recorded signature claims something the payload is not. The stamp is wrong (or was written by a build with a different layout); the payload is the truth.

Fields

field: &'static str

recorded: String

actual: String

Incompatible

The payload is coherent and honestly stamped, but it is not what this reader needs – a different model, a config change, a different block size.

Fields

field: &'static str

expected: String

found: String

BlockSizeMismatch

The stamp claims a block size the payload’s token depth is not. A stored block is exactly one whole block, so these are the same number or the stamp is wrong.

Fields

block_size: usize

tokens: usize

BadLayout(BlockLayoutError)

The block layout itself is not usable – most importantly, a block size that does not divide the sliding window. See kv_swa.

UnsupportedFormat

Written by a build whose payload layout this one cannot read.

Fields

found: u32

readable: &'static [u32]

Trait Implementations

impl Clone for SignatureError

fn clone(&self) -> SignatureError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureError

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

Formats the value using the given formatter.

impl Display for SignatureError

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

Formats the value using the given formatter.

impl Eq for SignatureError

impl Error for SignatureError

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<BlockLayoutError> for SignatureError

fn from(err: BlockLayoutError) -> Self

Converts to this type from the input type.

impl PartialEq for SignatureError

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

Equality operator ==.

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

Inequality operator !=.
