Errors that can occur during compression/decompression

Variants

Io(Error)

I/O error during compression/decompression

UnsupportedCompression(u8)

Unsupported compression format

InvalidMagic

Invalid magic bytes (not a compressed index)

IndexVersionTooNew

Index format version is too new

Fields

index_version: u32

Version number found in the index file

sqry_version: &'static str

Current sqry binary version

InvalidIndexVersion(u32)

Invalid format version (reserved value 0)

InvalidHeaderSize(usize)

Header is too small to be valid

SizeMismatch

Size mismatch after decompression

Fields

expected: u64

Expected uncompressed size from header

actual: u64

Actual size after decompression

DecompressionBomb

Decompression bomb detected (uncompressed size exceeds maximum)

Fields

size: u64

Declared uncompressed size

max: u64

Maximum allowed size

Trait Implementations

impl Debug for CompressionError

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

Formats the value using the given formatter.

impl Display for CompressionError

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

Formats the value using the given formatter.

impl Error for CompressionError

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 CompressionError

fn from(source: Error) -> Self

Converts to this type from the input type.
