Enum DecmpfsError 

pub enum DecmpfsError {
    Truncated,
    BadMagic(u32),
    UnknownType(u32),
    Unsupported(&'static str),
    MissingResourceFork,
    OutOfBounds,
    Codec(&'static str),
    LengthMismatch {
        expected: usize,
        got: usize,
    },
}

A decmpfs decode failure. Every arm fails loud — decmpfs never degrades to silent wrong output (a half-decoded file is worse than a named error).

Variants

Truncated

The xattr is shorter than the 16-byte header.

BadMagic(u32)

The header magic was not cmpf.

UnknownType(u32)

compression_type is not a documented value.

Unsupported(&'static str)

A documented but unsupported type (LZBitmap — no public spec; or the de-dup generation store, type 5, which has no payload here).

MissingResourceFork

An even (resource-fork) type was seen but no resource fork was supplied.

OutOfBounds

A length/offset field pointed outside the available bytes.

Codec(&'static str)

The underlying codec rejected the stream.

LengthMismatch

The decoded output length did not match the header’s uncompressed_size.

Fields

expected: usize

uncompressed_size from the header.

got: usize

Bytes actually produced.

Trait Implementations

impl Clone for DecmpfsError

fn clone(&self) -> DecmpfsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecmpfsError

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

Formats the value using the given formatter.

impl Display for DecmpfsError

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

Formats the value using the given formatter.

impl Eq for DecmpfsError

impl Error for DecmpfsError

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 PartialEq for DecmpfsError

fn eq(&self, other: &DecmpfsError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
