Enum rust_unixfs::dir::ResolveError

pub enum ResolveError {
    UnexpectedType(UnexpectedNodeType),
    UnexpectedDirProperties(UnexpectedDirectoryProperties),
    Read(Error),
    Lookup(LookupError),
}

Resolving can fail similarly as with ShardedLookup::continue_walk but in addition to sharded cases, there can be unexpected directories.

Variants

UnexpectedType(UnexpectedNodeType)

The target block was a UnixFs node that doesn’t support resolving, e.g. a file.

UnexpectedDirProperties(UnexpectedDirectoryProperties)

A directory had unsupported properties. These are not encountered during walking sharded directories.

Read(Error)

Failed to read the block as a dag-pb node. Failure to read an inner UnixFS node is ignored and links of the outer dag-pb are processed.

Lookup(LookupError)

Lookup errors.

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, fmt: &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.
