Enum Error

#[non_exhaustive]
pub enum Error {
    Lmdb(Error),
    BytesRepr(Error),
    Poison,
    Commit(CommitError),
    RootNotFound,
    MissingTrieNodeChildren(Digest, TrieRaw, Vec<Digest>),
    FailedToPrune(Vec<Key>),
    CannotProvideProofsOverCachedData,
    CacheError(CacheError),
}

Error enum representing possible errors in global state interactions.

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.

Lmdb(Error)

LMDB error returned from underlying lmdb crate.

BytesRepr(Error)

(De)serialization error.

Poison

Concurrency error.

Commit(CommitError)

Error committing to execution engine.

RootNotFound

Invalid state root hash.

MissingTrieNodeChildren(Digest, TrieRaw, Vec<Digest>)

Failed to put a trie node into global state because some of its children were missing.

FailedToPrune(Vec<Key>)

Failed to prune listed keys.

CannotProvideProofsOverCachedData

Cannot provide proofs over working state in a cache (programmer error).

CacheError(CacheError)

Encountered a cache error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<CommitError> for Error

fn from(source: CommitError) -> Self

Converts to this type from the input type.

impl From<Error> for BurnError

fn from(gse: GlobalStateError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(gse: Error) -> Self

Converts to this type from the input type.

impl From<Error> for StepError

fn from(gse: GlobalStateError) -> Self

Converts to this type from the input type.

impl From<Error> for TransferError

fn from(gse: GlobalStateError) -> Self

Converts to this type from the input type.

impl<T> From<PoisonError<T>> for Error

fn from(_error: PoisonError<T>) -> Self

impl PartialEq for Error

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