Errors that can occur during encoding or decoding.

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.

Truncated

Input data is too short or truncated.

Fields

expected: usize

actual: usize

Corrupt

Input data is corrupted (invalid header, bad checksum, etc.).

Fields

detail: String

DecompressFailed

Decompression failed (LZ4/Zstd library error).

Fields

detail: String

CompressFailed

Compression failed (LZ4/Zstd library error).

Fields

detail: String

CodecMismatch

The codec stored in metadata doesn’t match the expected codec.

Fields

expected: String

found: String

LayoutError

Invalid layout construction or access (vector quantization).

Fields

detail: String

UnresolvedAuto

ColumnCodec::Auto reached a point where a concrete codec was required.

Auto is a user-facing selection hint that must be resolved to a concrete codec at flush time. If Auto appears in a serialized on-disk header or is passed directly to an encoder, the write path has a bug — ColumnCodec::try_resolve() was not called.

UnknownCodec

A codec name string did not match any canonical form.

Canonical names are lowercase snake_case exactly as returned by ColumnCodec::as_str(). No case-insensitive matching; no hyphen or space variants. The error message lists all valid names.

Fields

name: String

valid: &'static str

Trait Implementations

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

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.
