Error type.

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.

Failed

Operation failed due to previous error

InvalidClass

Fields

value: u8

Class has more than 2 bytes

InvalidTag

Fields

byte: u8

Raw byte value of the tag

Invalid tag

InvalidLength

Length greater than u16::MAX

Length

Fields

tag: Tag

Tag type of the value being decoded

Incorrect length for a given field

Overflow

Integer overflow occurred (library bug!)

Overlength

Message is longer than BER-TLV’s limits support

TrailingData

Fields

decoded: Length

Length of the decoded data

remaining: Length

Total length of the remaining data left in the buffer

Undecoded trailing data at end of message

Truncated

Unexpected end-of-message/nested field when decoding

Underlength

Fields

expected: Length

Expected length

actual: Length

Actual length

Encoded message is shorter than the expected length (i.e. an Encodable impl on a particular type has a buggy encoded_length)

UnexpectedTag

Fields

expected: Option<Tag>

Tag the decoder was expecting (if there is a single such tag).

None if multiple tags are expected/allowed, but the actual tag does not match any of them.

actual: Tag

Actual tag encountered in the message

Unexpected tag

UnsupportedTagSize

Tag does not fit in 3 bytes

Implementations

impl ErrorKind

pub fn at(self, position: Length) -> Error

Annotate an ErrorKind with context about where it occurred, returning an error.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Error

Converts to this type from the input type.

impl PartialEq for ErrorKind

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

This method tests for self and other values to be equal, and is used by ==.

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

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