Why a block is not a value in this data model.

Variants

Truncated(usize)

The block ended in the middle of a value.

Trailing(usize)

A value was complete and bytes followed it. A block is one value.

NonCanonicalArgument

An argument written in a wider form than the shortest that holds it.

Fields

argument: u64

The number that was written.

width: usize

How many bytes it was written in.

IndefiniteLength

One of the indefinite-length forms, which DAG-CBOR does not have.

ReservedArgument(u8)

A reserved additional-information value: 28, 29 or 30.

Float

A float, of any width. The data model has no float; see Value.

Simple(u8)

A simple value other than false, true and null.

IntegerRange(u64)

An integer past what an i64 holds, which the data model’s one number type cannot carry.

NotUtf8

A text string, or a map key, that is not UTF-8.

Tag(u64)

A tag other than 42.

LinkNotBytes

Tag 42 over something that is not a byte string.

LinkPrefix

A link’s byte string without the identity multibase prefix.

Link(CidError)

A link whose bytes are not a CID this crate can re-encode.

KeyNotText

A map key that is not a text string.

KeyOrder

Map keys out of order, which includes a repeated key.

Fields

found: String

The key that was read.

previous: String

The key before it.

TooDeep

More nesting than MAX_DEPTH.

Trait Implementations

impl Clone for CborError

fn clone(&self) -> CborError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CborError

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

Formats the value using the given formatter.

impl Display for CborError

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

Formats the value using the given formatter.

impl Error for CborError

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<CborError> for NodeError

fn from(source: CborError) -> Self

Converts to this type from the input type.

impl From<CidError> for CborError

fn from(source: CidError) -> Self

Converts to this type from the input type.

impl PartialEq for CborError

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

Tests for self and other values to be equal, and is used by ==.

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

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