Enum ErrorCause

#[non_exhaustive]
pub enum ErrorCause {
    #[non_exhaustive]
    DIDParsingError {
        source: Box<dyn Error + Sync + Send>,
    },
    #[non_exhaustive]
    HandlerError {
        source: Box<dyn Error + Sync + Send>,
    },
    UnsupportedMethodError {
        method: String,
    },
    UnsupportedNetwork(String),
}

Error failure modes associated with the methods on the Resolver’s.

NOTE: This is a “read only error” in the sense that it can only be constructed by the methods in this crate.

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.

DIDParsingError

Caused by a failure to parse a DID string during DID resolution.

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.

source: Box<dyn Error + Sync + Send>

The source of the parsing error.

HandlerError

A handler attached to the Resolver attempted to resolve the DID, but the resolution did not succeed.

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.

source: Box<dyn Error + Sync + Send>

The source of the handler error.

UnsupportedMethodError

Caused by attempting to resolve a DID whose method does not have a corresponding handler attached to the Resolver.

Fields

method: String

The method that is unsupported.

UnsupportedNetwork(String)

No client attached to the specific network.

Trait Implementations

impl Debug for ErrorCause

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

Formats the value using the given formatter.

impl Display for ErrorCause

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

Formats the value using the given formatter.

impl Error for ErrorCause

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<'_derivative_strum> From<&'_derivative_strum ErrorCause> for &'static str

fn from(x: &'_derivative_strum ErrorCause) -> &'static str

Converts to this type from the input type.

impl From<ErrorCause> for &'static str

fn from(x: ErrorCause) -> &'static str

Converts to this type from the input type.
