}

Errors that can happen during deserialization.

Variants

FileOpenError(Error)

Deserialize::load_full could not open the provided file.

ReadError

The underlying reader returned an error.

EndiannessError

The file is from ε-serde but the endianness is wrong.

AlignmentError

Some fields are not properly aligned.

MajorVersionMismatch(u16)

The file was serialized with a version of ε-serde that is not compatible.

MinorVersionMismatch(u16)

The file was serialized with a compatible, but too new version of ε-serde so we might be missing features.

UsizeSizeMismatch(usize)

The pointer width of the serialized file is different from the pointer width of the current architecture. For example, the file was serialized on a 64-bit machine and we are trying to deserialize it on a 32-bit machine.

MagicCookieError(u64)

The magic cookie is wrong. The byte sequence does not come from ε-serde.

InvalidTag(usize)

A tag is wrong (e.g., for Option).

WrongTypeHash

The type hash is wrong. Probably the user is trying to deserialize a file with the wrong type.

Fields

ser_type_name: String

ser_type_hash: u64

self_type_name: String

self_ser_type_name: String

self_type_hash: u64

WrongAlignHash

The type representation hash is wrong. Probably the user is trying to deserialize a file with some zero-copy type that has different in-memory representations on the serialization arch and on the current one, usually because of alignment issues. There are also some backward-compatibility issues discussed in the error message.

Fields

ser_type_name: String

ser_align_hash: u64

self_type_name: String

self_ser_type_name: String

self_align_hash: u64

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
