Errors returned while parsing a $I index file.

Variants

TruncatedHeader

The file is shorter than the 24-byte fixed header.

Fields

got: usize

Number of bytes actually present.

UnsupportedVersion

The 8-byte version field at offset 0 is neither 1 nor 2.

Fields

version: u64

The version value as read.

raw: u64

The raw little-endian bytes, for the investigator.

TruncatedV1Name

A version-1 file does not contain the full fixed 520-byte name field.

Fields

got: usize

Bytes present.

needed: usize

Bytes required (24 + 520).

TruncatedV2Length

A version-2 file is too short to hold the 4-byte name-length field.

Fields

got: usize

Bytes present.

needed: usize

Bytes required (24 + 4).

NameLengthTooLarge

The version-2 name-length field exceeds [MAX_V2_NAME_CHARS] — rejected before allocating to defend against a hostile length.

Fields

chars: u32

The offending character count.

TruncatedV2Name

The version-2 name-length field claims more bytes than the file holds.

Fields

got: usize

Bytes present after the length field.

needed: usize

Bytes the length field demands.

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 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: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
