Enum FormatError 

pub enum FormatError {

    UnsupportedVersion(u16),
    Truncated,

}

Errors produced while reading or writing .rec data.

Malformed input is reported through these variants and never panics.

Variants

Io(Error)

An underlying I/O operation failed.

BadMagic([u8; 4])

The file does not start with the TKWS magic.

BadTrailerMagic([u8; 4])

The file does not end with the TKWE trailer magic.

UnsupportedVersion(u16)

The file was written by a newer format version than this build reads.

Truncated

The data ends before a complete structure could be read.

TooLarge

A declared length exceeds the format’s safety limits.

InvalidUtf8

A string field holds bytes that are not valid UTF-8.

ChecksumMismatch

The stored checksum does not match the recomputed one.

Fields

stored: u64

Checksum stored in the trailer.

computed: u64

Checksum recomputed from the file bytes.

Corrupt(&'static str)

A structural invariant does not hold, with a short reason.

Trait Implementations

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Error for FormatError

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.
