All errors that the SEGB reader can produce.

Variants

Io(Error)

The file / stream produced an I/O error.

BadMagic

The magic bytes at the expected position do not match SEGB.

Fields

found: String

TruncatedHeader

The file header is shorter than expected.

Fields

need: usize

got: usize

TruncatedRecordHeader

A record header is shorter than expected.

Fields

offset: u64

need: usize

got: usize

TruncatedPayload

A record payload is shorter than the length field claims.

Fields

offset: u64

need: usize

got: usize

InvalidLength

A record_length value is negative, which is not valid.

Fields

offset: u64

length: i32

InvalidEntryCount

entries_count in a SEGB v2 header is negative.

Fields

count: i32

TrailerOverflow

The trailer size overflows the file size in SEGB v2.

Fields

trailer_bytes: u64

stream_bytes: u64

UnknownState(i32)

An EntryState byte did not map to a known variant.

InvalidSeek(String)

A seek operation was asked to go to a negative or overflow position.

MalformedVarint

A protobuf varint was longer than 10 bytes (malformed).

Fields

offset: usize

ProtobufOverflow

A protobuf length-delimited field extends past the buffer end.

Fields

offset: usize

length: usize

remaining: usize

Trait Implementations

impl Debug for SegbError

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

Formats the value using the given formatter.

impl Display for SegbError

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

Formats the value using the given formatter.

impl Error for SegbError

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 SegbError

fn from(source: Error) -> Self

Converts to this type from the input type.
