Enum BlockFormatError 

pub enum BlockFormatError {
    TooShort {
        len: usize,
    },
    BadMagic,
    UnsupportedFormat {
        found: u32,
        readable: &'static [u32],
    },
    Truncated {
        expected: u64,
        actual: u64,
    },
    ChecksumMismatch,
    Malformed(&'static str),
    UnknownDtype(u32),
    BadLayout(BlockLayoutError),
}

Why a block file was refused. Every variant means “these bytes are not a block this build can read”, and none of them is recoverable by reading harder.

Variants

TooShort

Shorter than the fixed prefix: there is not even a header to check.

Fields

len: usize

BadMagic

Not a ferrox block file at all.

UnsupportedFormat

Written by a build whose layout this one does not know.

Fields

found: u32

readable: &'static [u32]

Truncated

The file’s own declared length does not match the bytes present – a half-written or truncated file.

Fields

expected: u64

actual: u64

ChecksumMismatch

Right length, wrong bytes: bit rot, an interrupted overwrite, or a file that was edited.

Malformed(&'static str)

Structurally impossible content: a dimension of zero, a body that cannot hold the tensors the header describes.

UnknownDtype(u32)

A dtype code this build has no reader for.

BadLayout(BlockLayoutError)

The recorded block layout is not one any correct writer could have produced – a block size that does not divide the sliding window it was cut against.

Trait Implementations

impl Clone for BlockFormatError

fn clone(&self) -> BlockFormatError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockFormatError

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

Formats the value using the given formatter.

impl Display for BlockFormatError

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

Formats the value using the given formatter.

impl Eq for BlockFormatError

impl Error for BlockFormatError

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 BlockFormatError

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

Equality operator ==.

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

Inequality operator !=.
