Enum BlockchainError 

pub enum BlockchainError {
    ConflictRetry {
        expected: [u8; 32],
        got: [u8; 32],
    },
    Immutable,
}

Operational errors surfaced by the blockchain engine path.

Variants

ConflictRetry

Client submitted a prev_hash that no longer matches the current tip (someone else appended first). Surface as HTTP 409.

Fields

expected: [u8; 32]

got: [u8; 32]

Immutable

Caller attempted UPDATE or DELETE on a KIND blockchain collection. Surface as HTTP 409 (BlockchainCollectionImmutable).

Trait Implementations

impl Clone for BlockchainError

fn clone(&self) -> BlockchainError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockchainError

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

Formats the value using the given formatter.

impl Display for BlockchainError

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

Formats the value using the given formatter.

impl Error for BlockchainError

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 BlockchainError

fn eq(&self, other: &BlockchainError) -> 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.
