Generic error type for Invocation use cases.

Variants

CidEncode(Error)

Error encoding structure to a Cid.

ConditionNotMet(String)

Error thrown when condition or dynamic check is not met.

DagCborTranslation(Error)

Failure to decode/encode from/to DagCbor.

The underlying error is a anyhow::Error, per the DagCborCodec implementation.

FromIpld(SerdeError)

Error converting from [Ipld] structure via serde.

Transparently forwards from [libipld::error::SerdeError]’s source and Display methods through to an underlying error.

InvalidDiscriminant(T)

Invalid match discriminant or enumeration.

MissingField(String)

Error related to a missing a field in a structure or key in a map.

ParseResource(ParseError)

Error during parsing a Url.

Transparently forwards from url::ParseError’s source and Display methods through to an underlying error.

Unknown

Generic unknown error.

UnexpectedIpldType(Ipld)

Unexpcted [Ipld] type.

Utf8(Utf8Error)

Error when attempting to interpret a sequence of u8 as a string.

Transparently forwards from std::str::Utf8Error’s source and Display methods through to an underlying error.

Io(Error)

Propagated IO error.

Implementations

impl<T> Error<T>

pub fn unexpected_ipld(ipld: Ipld) -> Self

Return a SerdeError when returning an [Ipld] structure that’s not expected at the call-site.

pub fn not_an_ipld_list() -> Self

Return an invalid type SerdeError when not matching an expected [Ipld] list/sequence type.

Trait Implementations

impl<T: Debug> Debug for Error<T>

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

Formats the value using the given formatter.

impl<T> Display for Error<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Error for Error<T>

where Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
