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

InvalidTag

Invalid tag

Fields

byte: u8

Raw byte value of the tag

InvalidLength

Length greater than u16::MAX

Length

Incorrect length for a given field

Fields

tag: Tag

Tag type of the value being decoded

Overflow

Integer overflow occurred (library bug!)

Overlength

Message is longer than SIMPLE-TLV’s limits support

TrailingData

Undecoded trailing data at end of message

Fields

decoded: Length

Length of the decoded data

remaining: Length

Total length of the remaining data left in the buffer

Truncated

Unexpected end-of-message/nested field when decoding

Underlength

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

Fields

expected: Length

Expected length

actual: Length

Actual length

UnexpectedTag

Unexpected tag

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
