Errors that can occur while decoding an .ithmb thumbnail.

Every variant carries a human-readable detail string or structured fields.

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.

Io(String)

An I/O-level failure (e.g. end of stream, read error).

Jpeg(String)

A JPEG decode failure (corrupt or unsupported JPEG data).

InvalidFormat(String)

The file format is invalid or unrecognized.

Unsupported(String)

The format is recognized but not supported by this decoder.

BufferTooShort

The input buffer ended before the expected amount of data was consumed.

Fields

expected: usize

Number of bytes the decoder expected.

actual: usize

Actual number of bytes available.

Profile(String)

A decoder profile mismatch or configuration error.

Canceled(String)

The operation was canceled by the caller.

FileTooLarge

The input file exceeds the maximum allowed size.

Fields

size: usize

Actual file size in bytes.

limit: usize

Maximum allowed size in bytes.

Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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.
