Why a string is not a valid DID, DID URL or DID method.

Positions are byte offsets into the input that was parsed.

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.

MissingScheme

The input does not start with the lowercase did: scheme.

InvalidMethodName

The method name is empty or contains a character other than a-z and 0-9.

Fields

position: usize

Byte offset of the offending character.

EmptyMethodSpecificId

The method-specific id is missing, empty, or ends with :.

InvalidNamespace

The namespace of a DidMethod is empty, has a second segment, or contains a character that is not an idchar.

Fields

position: usize

Byte offset of the offending character, or of the end of the input.

InvalidChar

A character that is not allowed at this position of a DID.

Fields

position: usize

Byte offset of the offending character.

ch: char

The offending character.

InvalidPercentEncoding

A % that is not followed by exactly two hexadecimal digits.

Fields

position: usize

Byte offset of the %.

TooLong

The input is longer than the configured maximum.

Fields

max: usize

The maximum number of bytes accepted.

InvalidPath

The DID URL path is not a valid RFC 3986 path-abempty.

InvalidQuery

The DID URL query contains a character not allowed by RFC 3986.

InvalidFragment

The DID URL fragment contains a character not allowed by RFC 3986.

UnsupportedNumber

The key of a did:jwk holds a JSON number with no finite double value, such as 1e400, which the JSON Canonicalization Scheme cannot encode. serde_json only keeps such a number when its arbitrary_precision feature is on.

Fields

number: String

The number as written.

Trait Implementations

impl Clone for DidError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DidError

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

Formats the value using the given formatter.

impl Display for DidError

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

Formats the value using the given formatter.

impl Eq for DidError

impl Error for DidError

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<DidError> for ResolutionError

fn from(error: DidError) -> Self

ResolutionErrorKind::InvalidDid, caused by error.

impl PartialEq for DidError

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

Equality operator ==.

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

Inequality operator !=.
