Enum CidError 

pub enum CidError {
    Empty,
    Multibase(char),
    NotBase32(DecodeError),
    BadVarint,
    Version(u64),
    Codec(u64),
    Multihash {
        code: u64,
        length: u64,
    },
    DigestLength {
        found: usize,
        expected: usize,
    },
}

Why a string or a byte sequence is not a CID this crate can use.

Variants

Empty

Empty, so there is not even a multibase prefix.

Multibase(char)

A multibase other than lowercase base32.

NotBase32(DecodeError)

The base32 body did not decode.

BadVarint

A varint that ran off the end of the input, or one too long to be a u64.

Version(u64)

A CID version other than 1, which includes every CIDv0.

Codec(u64)

A codec other than DAG-CBOR or raw.

Multihash

A multihash that is not a 32-byte sha-256.

Fields

code: u64

The multihash function code that was found.

length: u64

The digest length that was found.

DigestLength

Bytes after the digest, or fewer than the digest claimed.

Fields

found: usize

How many bytes actually followed the multihash header.

expected: usize

How many the header said there would be.

Trait Implementations

impl Clone for CidError

fn clone(&self) -> CidError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CidError

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

Formats the value using the given formatter.

impl Display for CidError

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

Formats the value using the given formatter.

impl Error for CidError

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<CidError> for CborError

fn from(source: CidError) -> Self

Converts to this type from the input type.

impl From<CidError> for ErrorKind

fn from(source: CidError) -> Self

Converts to this type from the input type.

impl From<DecodeError> for CidError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for CidError

fn eq(&self, other: &CidError) -> 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.
