Available on crate feature unstable only.

Reasons apply_stream_updates can reject a batch.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyBatch

A batch contained no commitments. The framework never folds an empty batch into the MMR, so a verifier should not produce one.

Fields

batch_index: usize

Index into the batches slice where the empty batch was found.

CommitmentCheckpointMismatch

A commitment’s checkpoint_seq field disagreed with the enclosing batch’s checkpoint_seq. A batch corresponds to a single settlement transaction; all of its commitments share the settlement’s checkpoint.

Fields

batch_index: usize

Index into the batches slice.

commitment_index: usize

Index into the offending batch’s commitments vector.

batch_checkpoint_seq: u64

The batch’s authoritative checkpoint sequence number.

commitment_checkpoint_seq: u64

The commitment’s contradictory checkpoint sequence number.

NonMonotonicCheckpoint

A batch’s checkpoint_seq was strictly less than the head’s last folded checkpoint. Batches must be applied in monotonic order.

Fields

batch_index: usize

Index into the batches slice.

previous_checkpoint_seq: u64

The head’s checkpoint_seq before this batch was attempted.

batch_checkpoint_seq: u64

The offending batch’s checkpoint_seq.

Trait Implementations

impl Clone for ApplyStreamError

fn clone(&self) -> ApplyStreamError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApplyStreamError

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

Formats the value using the given formatter.

impl Display for ApplyStreamError

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

Formats the value using the given formatter.

impl Eq for ApplyStreamError

impl Error for ApplyStreamError

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 PartialEq for ApplyStreamError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
