Enum StateProofError 

pub enum StateProofError {
    Database(DatabaseError),
    Rlp(Error),
    TrieInconsistency(String),
}

State proof errors.

Variants

Database(DatabaseError)

Internal database error.

Rlp(Error)

RLP decoding error.

TrieInconsistency(String)

Trie inconsistency detected during proof calculation.

This occurs when cached trie nodes disagree with the leaf data, causing proof calculation to be unable to make forward progress.

Trait Implementations

impl Clone for StateProofError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateProofError

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

Formats the value using the given formatter.

impl Display for StateProofError

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

Formats the value using the given formatter.

impl Error for StateProofError

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 #99301)

Provides type-based access to context intended for error reports.

impl From<DatabaseError> for StateProofError

fn from(source: DatabaseError) -> Self

Converts to this type from the input type.

impl From<Error> for StateProofError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<StateProofError> for ProviderError

fn from(value: StateProofError) -> Self

Converts to this type from the input type.

impl From<StateProofError> for TrieWitnessError

fn from(source: StateProofError) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
