Enum ipfs_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 not a directory, hamt shard, or was a dag-pb node whose data could not be parsed as UnixFS.

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 backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
