Crate-level error type for hurray-io.

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.

Io(Error)

An I/O error from the underlying stream or file.

Core(Error)

A core format error.

UnexpectedEof

The stream ended before a complete record was read.

InvalidHeader(String)

A frame or record header is malformed.

MultiBufferLengthMismatch

The number of supplied buffer slices does not match the descriptor’s buffer table.

Fields

declared: usize

actual: usize

BufferSizeMismatch

A supplied buffer’s byte length does not match the corresponding handle’s byte_size.

Fields

index: usize

declared: u64

actual: u64

FrameTooLarge

A descriptor or buffer exceeded the configured size limit.

Fields

kind: &'static str

value: u64

limit: u64

InvalidCrossMachineSyncMode

A buffer handle’s sync_mode is invalid for a cross-machine transport.

Fields

index: usize

actual: u8

TornComposite

A composite head’s members were truncated: the stream ended before the head’s declared member_count members had been read.

Fields

declared: u32

actual: u32

CompositeNestingTooDeep

Composite nesting exceeded the configured maximum depth. Guards against stack exhaustion from a maliciously deep composite on an untrusted stream.

Fields

limit: usize

NotAComposite(String)

A composite read was requested for a tensor whose head is not a composite.

InvalidFileMagic

The file header magic is not HRRYFILE.

InvalidTrailerMagic

The trailer magic is not HRRY.

UnsupportedContainerVersion

The container major version is higher than this reader supports.

Fields

major: u8

TensorNotFound(String)

A tensor name was requested but is not in the file index.

DuplicateTensorName(String)

Two tensors in the same file share a name.

TensorNameEmpty

A tensor name is empty.

TensorNameTooLong

A tensor name exceeds the 65 535-byte uint16 limit.

Fields

len: usize

IndexCrc32cMismatch

The index CRC-32C does not match the stored value.

Fields

stored: u32

computed: u32

DuplicateKvKey(String)

Two KV entries share the same key.

KvKeyEmpty

A KV key is empty.

KvKeyTooLong

A KV key exceeds the 65 535-byte uint16 limit.

Fields

len: usize

ReservedFileFlagBits

A reserved flag bit was set in the file header.

Fields

flags: u32

IndexOverrunsTrailer

The index section overlaps the trailer.

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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
