Enum AnchorError 

pub enum AnchorError {
    Checkpoint(CheckpointError),
    Chain(ChainError),
    BrokenAnchor {
        device_id: String,
        detail: String,
    },
    UnanchoredDevice {
        device_id: String,
        first_seq: u64,
    },
}

A failure composing a checkpoint with a (truncated) tail.

Variants

Checkpoint(CheckpointError)

The checkpoint itself doesn’t verify.

Chain(ChainError)

The tail doesn’t chain-verify on its own.

BrokenAnchor

A device’s first retained op doesn’t continue the checkpoint’s recorded frontier (seq, prev link, or HLC advance).

Fields

device_id: String

detail: String

UnanchoredDevice

A device absent from the checkpoint frontier must present its chain from seq 0 — a nonzero start with no anchor is a silent hole.

Fields

device_id: String

first_seq: u64

Trait Implementations

impl Debug for AnchorError

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

Formats the value using the given formatter.

impl Display for AnchorError

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

Formats the value using the given formatter.

impl Error for AnchorError

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<AnchorError> for SessionError

fn from(e: AnchorError) -> Self

Converts to this type from the input type.
