GASP protocol errors.

Variants

DefinitiveNotFound(String)

Every enabled raw rung answered absence, with no skipped or failed rung. Since engine 0.1.15 it counts one run of absence beside the peer’s word (fault_class::NOT_FOUND), never a strike by itself.

CourierBudget

The pass spent its courier allowance; retain its pending walk.

VersionMismatch

Version mismatch between peers.

Fields

local: u32

remote: u32

InvalidTimestamp(String)

Invalid timestamp format.

NodeNotFound(String)

Node not found.

ValidationFailed(String)

Graph validation failed.

RemoteError(String)

Network/communication error.

RouteFault

The platform answered before the peer was reached (engine 0.2.0, bsv-overlay-cloudflare #57; crate::route_fault): a fault of the route, never of the peer. It counts nothing against the peer’s health rows and is named route_fault:<class>.

Fields

class: String

detail: String

StorageError(String)

Storage error.

AnchorUnavailable(String)

A graph’s anchor could not be CHECKED right now (the chain tracker or a storage read faulted, or the topic manager answered the replay with an error): a fault of the moment, not a verdict on the graph. GASPSync::complete_graph discards the graph and fails the UTXO, so the cursor gap guard asks for it again (bsv-low #551).

AnchorWalkHeld(String)

The anchor’s script walk could not run within the engine’s walk budget (bsv-low #592; the E592 lens fold, H1): no verdict, and nothing stands in for one (no network accepted these bytes). Held exactly as GASPError::AnchorUnavailable holds: the graph is not finalized, the UTXO fails and the cursor stays below it, until the peer serves its root PROVEN (#555’s root_proven restart, whose walk trusts the proof and runs no script). Counted apart (GASPSync::anchor_walk_held).

Other(String)

Generic error.

Trait Implementations

impl Clone for GASPError

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 GASPError

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

Formats the value using the given formatter.

impl Display for GASPError

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

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
