Variants

Loading(Cid, Error)

Loading of the block on the path failed

UnsupportedDocument(Cid, Box<dyn StdError + Send + Sync + 'static>)

The document is unsupported; this can be a UnixFs directory structure which has unsupported options, or IPLD parsing failed.

ListIndexOutOfRange

Fields

document: Cid

The document with the mismatched index

path: SlashedPath

The path up until the mismatched index

index: usize

The index in original path

elements: usize

Total number of elements found

Path contained an index which was out of range for the given [Ipld::List].

NoLinks(Cid, SlashedPath)

Path attempted to resolve through e.g. a string or an integer.

NotFound(Cid, SlashedPath)

Path attempted to resolve through a property, index or link which did not exist.

NoCid(IpfsPath)

Tried to use a path neiter containing nor resolving to a Cid.

IpnsResolutionFailed(IpfsPath)

Couldn’t resolve a path via IPNS.

Trait Implementations

impl Debug for ResolveError

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

Formats the value using the given formatter.

impl Display for ResolveError

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

Formats the value using the given formatter.

impl Error for ResolveError

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
