Errors which can occur while walking a tree.

Variants

UnsupportedType(UnexpectedNodeType)

An unsupported type of UnixFS node was encountered. There should be a way to skip these. Of the defined types only Metadata is unsupported, all undefined types as of 2020-06 are also unsupported.

UnexpectedType(UnexpectedNodeType)

This error is returned when a file e.g. links to a non-Raw or non-File subtree.

DagPbParsingFailed(Error)

dag-pb node parsing failed, perhaps the block is not a dag-pb node?

UnixFsParsingFailed(Error)

Failed to parse the unixfs node inside the dag-pb node.

EmptyDagPbNode

dag-pb node contained no data.

InvalidCid(InvalidCidInLink)

dag-pb link could not be converted to a Cid

File(FileError)

A File has an invalid structure

UnsupportedDirectory(UnexpectedDirectoryProperties)

A Directory has an unsupported structure

UnsupportedHAMTShard(ShardError)

HAMTSharded directory has unsupported properties

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for Error

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

impl From<FileReadFailed> for Error

fn from(e: FileReadFailed) -> Self

impl From<InvalidCidInLink> for Error

fn from(e: InvalidCidInLink) -> Self

Performs the conversion.

impl From<ShardError> for Error
