Variants

Io(Error)

BadMagic

Fields

found: [u8; 8]

UnsupportedFormatVersion

Fields

found: u32

supported: u32

ArkFfVersionMismatch

Fields

found: String

expected: String

IdentifierTooLong

Fields

len: usize

max: usize

IdentifierMismatch

Fields

found: String

expected: String

IdentifierInvalidUtf8

DuplicateSectionTag

Fields

tag: u32

MissingSection

Fields

tag: u32

SectionLengthMismatch

Fields

tag: u32

expected: u64

found: u64

MisalignedSection

Fields

tag: u32

offset: u64

TruncatedFile

PayloadNotFieldAligned

Field element count in a payload does not divide the payload length cleanly.

Fields

tag: u32

length: u64

UnknownFeatureFlagBits

ConstraintSystem::feature_flags bitmap had an unknown bit set.

Fields

bits: u32

LookupConstraintSystem(String)

The lazily-built LookupConstraintSystem failed to materialise at write time (e.g. a lookup-table id collision or an over-long table). The wrapped string is the underlying LookupError’s message.

UnknownGateType

A pruned gate carried a type tag with no corresponding GateType.

Fields

tag: u16

InvalidDomainSize

The stored d1 domain size could not be turned into an evaluation domain (not a power of two, or too large for the field’s 2-adicity).

Fields

size: u64

Trait Implementations

impl Debug for CacheError

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

Formats the value using the given formatter.

impl Display for CacheError

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

Formats the value using the given formatter.

impl Error for CacheError

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<Error> for CacheError

fn from(e: Error) -> Self

Converts to this type from the input type.
