Error from Sha256::from_cidv1 and Sha256::from_cidv1_bytes.

#[non_exhaustive] at the type level and per variant, so new variants and new fields stay semver-additive.

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.

#[non_exhaustive]

UnsupportedMultibase

The string does not start with the multibase prefix b (lowercase base32, no padding). Other multibase encodings, including B (uppercase base32), are not accepted.

#[non_exhaustive]

InvalidBase32

A byte after the multibase prefix is outside the lowercase base32 alphabet a-z 2-7.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

at: u32

0-based byte index in the input string, saturated at u32::MAX.

byte: u8

The offending byte.

#[non_exhaustive]

NonCanonicalBase32

The base32 text has a length no byte string encodes to, or its unused trailing bits are not zero, so it is not the canonical encoding of any binary CID.

#[non_exhaustive]

WrongLength

The binary CID is not 36 bytes long.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

got: u32

The actual byte length, saturated at u32::MAX.

#[non_exhaustive]

UnsupportedPrefix

The first four bytes are not 0x01 0x55 0x12 0x20, so the CID is not a version 1, raw, sha2-256 CID.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

got: [u8; 4]

The four bytes found.

impl Eq for CidV1Error

impl Error for CidV1Error

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
