One exact-hydration failure, with enough structure for callers to decide whether to retry, re-warm, or reject a candidate.

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.

ProofFetcherUnavailable

The cache has no account-proof callback installed.

Fields

address: Address

Account that could not be refreshed.

ProofResultMissing

The callback returned no result for a requested account.

Fields

address: Address

Requested account omitted by the callback.

ProofResultDuplicate

The callback returned more than one result for a requested account.

Fields

address: Address

Requested account with ambiguous results.

ProofResultUnexpected

The callback returned a result for an account that was not requested.

Fields

address: Address

Unrequested account returned by the callback.

StorageSlotDuplicate

A successful account proof returned one requested storage slot more than once, making its value ambiguous.

Fields

address: Address

Account whose proof contained the duplicate slot.

slot: U256

Requested slot returned more than once.

StorageSlotUnexpected

A successful account proof returned a storage slot that was not requested.

Fields

address: Address

Account whose proof contained the unrequested slot.

slot: U256

Unrequested slot returned by the callback.

ProofFetch

The provider or custom callback failed for one requested account.

Fields

address: Address

Account whose proof failed.

source: StorageFetchError

Typed provider/callback failure.

RuntimeCodeUnavailable

A deployed account’s runtime code is not resident, so its code identity cannot be validated from a hash-only proof.

Fields

address: Address

Deployed account requiring runtime code.

code_hash: B256

Code hash reported by the exact-block account proof.

StorageSlotMissing

A successful account proof omitted one requested storage slot.

Fields

address: Address

Account whose proof was incomplete.

slot: U256

Requested slot omitted from the proof result.

Trait Implementations

impl Clone for ReadSetHydrationFailure

fn clone(&self) -> ReadSetHydrationFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadSetHydrationFailure

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

Formats the value using the given formatter.

impl Display for ReadSetHydrationFailure

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

Formats the value using the given formatter.

impl Error for ReadSetHydrationFailure

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>)
