Variants

Io(Error)

Underlying I/O operation failed.

InvalidCachePath(String)

Source path or cache path is not valid for a project cache.

InvalidCacheName(String)

Project name or cache name contains unsupported characters.

UnsupportedCodec(MachineCacheCodec)

Requested codec is not supported by the typed cache helper yet.

UnsupportedCodecId(u32)

Cache bytes specified an unknown codec ID.

Serialization(String)

RKYV serialization failed.

InvalidMagic

Header magic did not match typed machine cache bytes.

UnsupportedVersion(u32)

Header version is not supported.

InvalidHeaderLength(u32)

Header length was not the expected fixed size.

ReservedBytesSet

Header reserved bytes or flags were non-zero.

LengthMismatch

Payload length in the header did not match file bytes.

SourceMismatch

Source fingerprint did not match the authoritative source file.

SchemaMismatch

Schema identity did not match the expected typed payload.

PayloadChecksumMismatch

Payload checksum did not match.

ArchiveChecksumMismatch

Archive checksum did not match.

BytecheckFailed(String)

RKYV byte validation failed.

Trait Implementations

impl Debug for MachineCacheError

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

Formats the value using the given formatter.

impl Display for MachineCacheError

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

Formats the value using the given formatter.

impl Error for MachineCacheError

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 MachineCacheError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<MachineCacheError> for MachineCacheMiss

fn from(source: MachineCacheError) -> Self

Converts to this type from the input type.
