Available on crate feature legacy only.

Why a frame of the v0.5, v0.6 or v0.7 format could not be decoded.

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

The input ends inside the frame.

UnsupportedParameter

The frame header sets a reserved bit or asks for a window the format does not allow.

Corrupted

The frame is malformed; reason names the structure that is.

Fields

reason: &'static str

What failed to decode.

OutputTooSmall

The output buffer is too small for the frame’s content.

DictionaryCorrupted

The dictionary could not be read.

DictionaryMismatch

The frame needs a dictionary with another ID than the one supplied.

Fields

expected: u32

The ID the frame names.

provided: u32

The ID of the dictionary supplied, 0 for none.

ChecksumMismatch

The 22-bit content checksum of a v0.7 frame does not match its output.

Fields

expected: u32

The value the frame stores.

calculated: u32

The value computed over the output.

Implementations

impl LegacyFrameError

pub fn code(&self) -> ErrorCode

The code libzstd returns for the same failure.

Trait Implementations

impl Clone for LegacyFrameError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LegacyFrameError

impl Debug for LegacyFrameError

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

impl Eq for LegacyFrameError

impl Error for LegacyFrameError

Available on crate feature std only.

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<LegacyFrameError> for FrameDecoderError

fn from(err: LegacyFrameError) -> Self
