Expand description

Errors which can occur while walking a tree.

Variants

UnsupportedType

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.

Tuple Fields of UnsupportedType

0: UnexpectedNodeType

UnexpectedType

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

Tuple Fields of UnexpectedType

0: UnexpectedNodeType

DagPbParsingFailed

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

Tuple Fields of DagPbParsingFailed

0: Error

UnixFsParsingFailed

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

Tuple Fields of UnixFsParsingFailed

0: Error

EmptyDagPbNode

dag-pb node contained no data.

InvalidCid

dag-pb link could not be converted to a Cid

Tuple Fields of InvalidCid

0: InvalidCidInLink

File

A File has an invalid structure

Tuple Fields of File

0: FileError

UnsupportedDirectory

A Directory has an unsupported structure

Tuple Fields of UnsupportedDirectory

0: UnexpectedDirectoryProperties

UnsupportedHAMTShard

HAMTSharded directory has unsupported properties

Tuple Fields of UnsupportedHAMTShard

0: ShardError
