A format, resource, or transformation failure. No I/O is performed by CRAFT.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidFrameSize

A zero or unsupported maximum frame length.

InvalidMetadata

A length, count, profile, or index is inconsistent.

UnsupportedVersion

This metadata format version is not supported.

UnsupportedSchemaVersion

Only the metadata schema introduced in craft-codec 0.2.0 is supported.

CompressionUnavailable

The metadata requires a compression codec whose feature is disabled.

EncryptionUnavailable

The metadata requires an encryption codec whose feature is disabled.

InvalidRange

The logical range is reversed or outside the object.

FrameAfterFinal

A full frame was submitted after a short final frame.

InvalidStoredLength

The buffer does not have the expected stored length.

ProfileMismatch

The descriptor and the decoder use different configurations.

UsageLimit

The configured cryptographic usage limit was reached.

Overflow

An integer or platform buffer limit would be exceeded.

Allocation

A buffer or index allocation failed.

CompressionFailed

The compression operation failed.

DecompressionFailed

Invalid compressed bytes or an incorrect decoded length.

EncryptionFailed

Encryption failed.

AuthenticationFailed

The frame did not authenticate.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

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: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
