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
