Why a pool, or one of its operations, failed.

Variants

NoSeeds

A pool given no seed station.

SeedNotPinned(String)

A seed without the station’s node_id, as host:port: a pool dials only stations it can check.

TooManySeeds

More seeds than max_seeds.

Fields

given: usize

max: usize

RealmTrustInvalid([u8; 32])

A realm key that is not a well-formed key of the pool’s profile, and its realm.

InvalidOpts(String)

An option out of its range, or a key that is no identity key.

NoLink(Vec<LinkError>)

No link came up within the connect timeout, or none is up to carry an operation; each link’s last error.

Closed

An operation on a closed pool.

NoRealmKey

A realm the pool pins no key for: nothing in it is served or trusted.

NoProvider(Vec<(Provider, PoolError)>)

No provider the pinned realm key authorizes answered: each candidate tried and why it failed; none when there was no candidate at all.

NoStationEndpoint(Option<LinkError>)

A serving station with no endpoint record it signed itself.

DirectLinksFull

A serving station not yet linked while max_direct_links direct links are held.

StationNotReached

A station that could not be linked, and the last dial’s error.

Fields

station: [u8; 32]

cause: Option<LinkError>

NotServed(Vec<LinkError>)

A procedure no link would serve, and each link’s error.

Link(LinkError)

A link’s own failure, or a provider’s or station’s answer.

NotShared

Content no node announces in the realm, or a sharer that does not hold it.

ContentUnavailable(Vec<([u8; 32], PoolError)>)

Content every announcing sharer failed to give: each sharer’s node and why.

ContentMismatch(String)

A block, manifest or whole that does not match the content id it was asked for by, and which.

ContentTooLarge(String)

Content over the fetch’s bounds, and how large.

ContentReply(String)

An answer a sharer never gives, and what it was.

Confidentiality(ConfidentialityError)

A call or an open that could not be kept confidential, so nothing was sent.

Trait Implementations

impl Clone for PoolError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PoolError

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

Formats the value using the given formatter.

impl Display for PoolError

impl Eq for PoolError

impl Error for PoolError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<LinkError> for PoolError

fn from(e: LinkError) -> Self

Converts to this type from the input type.

impl PartialEq for PoolError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
