Enum SubstrateStateMachineError 

pub enum SubstrateStateMachineError {
    ProofDecodeError(Error),
    MissingChildTrieRoot,
    TrieError(String),
    MissingMembershipValue(Vec<u8>),
    DeliveredRequestsInBatch,
}

Errors produced by the substrate state machine client.

Variants

ProofDecodeError(Error)

Failed to SCALE-decode the supplied proof.

MissingChildTrieRoot

The state commitment doesn’t include the child trie root, and the request state machine is not the coprocessor.

TrieError(String)

The trie backend returned an error while reading a key.

MissingMembershipValue(Vec<u8>)

A membership proof omitted the value for one of the requested keys.

DeliveredRequestsInBatch

A non-membership proof contained at least one delivered request.

Trait Implementations

impl Debug for SubstrateStateMachineError

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

Formats the value using the given formatter.

impl Display for SubstrateStateMachineError

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

Formats the value using the given formatter.

impl Error for SubstrateStateMachineError

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<SubstrateStateMachineError> for Error

fn from(e: SubstrateStateMachineError) -> Error

Converts to this type from the input type.
