codec 操作のエラー型。anyhow::Error ではなく専用型にすることで、上位 (S4Service) が HTTP エラーコードを意味的に出し分けやすくする。

TruncatedStream

v0.8.4 #73 M2: streaming compress consumed fewer input bytes than the caller advertised (typically a client disconnect mid-PUT). Surfaced from streaming::streaming_compress_to_frames when its expected_size = Some(n) argument is supplied; the s4-server PUT handler maps this to a 400 BadRequest so the client cannot rely on silent success of a half-uploaded body.

Fields

expected: u64

got: u64

ManifestSizeExceedsLimit

v0.8.5 #83 H-3: nvCOMP decompress refused to honour a manifest whose original_size exceeds the safety ceiling (default 5 GiB — AWS S3 single-PUT max). Without this gate, a forged or corrupted manifest can drive a Vec::with_capacity(huge) and trip an OOM before the CRC check ever runs. Distinct from SizeMismatch because here the manifest itself is rejected pre-allocation rather than a post-decompress length comparison.

Fields

requested: u64

limit: u64

ManifestSizeMismatch

v0.8.5 #83 H-3: nvCOMP decompress saw a manifest whose compressed_size field disagrees with the actual input payload length. Surfaced before allocation so a forged header can’t drive a sized read against truncated or padded input. Distinct from SizeMismatch (which is the post-decompress original-size check): this is a pre-flight check on the compressed side.

Fields

manifest: u64

actual: u64

Trait Implementations

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

fn source(&self) -> Option<&(dyn Error + 'static)>

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
