Enum ipfs_unixfs::LookupError

pub enum LookupError {
    Multiple(MultipleMatchingLinks),
    InvalidCid(InvalidCidInLink),
    UnexpectedBucketType(UnexpectedNodeType),
    Shard(ShardError),
    Read(Option<Error>),
}

Errors which can occur when looking up a HAMTSharded directory.

Variants

Multiple(MultipleMatchingLinks)

Multiple matching links were found

InvalidCid(InvalidCidInLink)

Invalid Cid was matched

UnexpectedBucketType(UnexpectedNodeType)

Unexpected HAMT shard bucket type

Shard(ShardError)

Unsupported or unexpected property of the UnixFS node

Read(Option<Error>)

Parsing failed or the inner dag-pb data was contained no bytes.

Implementations

impl LookupError

pub fn into_resolve_error(self) -> ResolveError

Converts this HAMT lookup error to the more general ResolveError

Trait Implementations

impl Debug for LookupError

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

Formats the value using the given formatter.

impl Display for LookupError

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

Formats the value using the given formatter.

impl Error for LookupError

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()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
