Errors produced while constructing, parsing, or serializing TR-31 optional blocks.

Variants

StringTooShort

The supplied optional-block string does not contain the minimum ID and length fields.

Fields

minimum: usize

actual: usize

NonAsciiInput

Optional blocks are defined using ASCII data and cannot safely be parsed from arbitrary UTF-8 strings.

ExtendedLengthStringTooShort

An extended-length optional block must contain at least 256 bytes.

Fields

minimum: usize

actual: usize

StringTooShortForLength

The encoded optional-block length exceeds the available input.

Fields

required: usize

actual: usize

Uninitialized

An optional block has not been initialized sufficiently for export.

Fields

length: usize

InvalidId(String)

The optional-block identifier is not supported.

IdNotSet

Data was assigned before an optional-block identifier.

NonAsciiData(String)

Optional-block data contains non-ASCII characters.

BlockTooLong

The complete optional block exceeds the maximum representable size.

Fields

maximum: usize

actual: usize

InvalidLengthFieldWidth

A normal length field must consist of exactly two hexadecimal characters.

Fields

value: String

expected: usize

InvalidLengthFieldHex

A normal length field is not valid hexadecimal.

Fields

value: String

source: ParseIntError

LengthFieldTooSmall

A normal optional-block length cannot be smaller than four bytes.

Fields

minimum: usize

actual: usize

InvalidExtendedLengthField(String)

An extended length field must consist of exactly six characters.

InvalidLengthOfLengthField(String)

The first two characters of the extended length field must encode the supported length-of-length value.

InvalidExtendedLengthHex

The extended block length is not valid hexadecimal.

Fields

value: String

source: ParseIntError

ExtendedLengthTooSmall

Extended encoding may only be used for block lengths greater than 255 bytes.

Fields

value: String

Trait Implementations

impl Debug for OptBlockError

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

Formats the value using the given formatter.

impl Display for OptBlockError

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

Formats the value using the given formatter.

impl Error for OptBlockError

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<OptBlockError> for KeyBlockHeaderError

fn from(error: OptBlockError) -> Self

Converts to this type from the input type.
