}

All failure modes during DVPL encode/decode.

Returned by encode and decode to describe exactly what went wrong.

Variants

TooSmall(usize)

Input shorter than 20 bytes (footer size).

BadMagic([u8; 4])

Footer magic does not match b"DVPL".

SizeMismatch

Payload length disagrees with the compressed_size field in the footer.

Fields

expected: usize

actual: usize

CrcMismatch

CRC32 of the payload does not match the checksum in the footer.

Fields

expected: u32

actual: u32

DecompressedSizeMismatch

Decompressed output length disagrees with the original_size field.

Fields

expected: usize

actual: usize

UnknownCompression(u32)

Footer contains an unrecognized compression type value.

Lz4(String)

Upstream lz4 crate returned an error during compress/decompress.

Trait Implementations

impl Debug for DvplError

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

Formats the value using the given formatter.

impl Display for DvplError

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

Formats the value using the given formatter.

impl Error for DvplError

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.
