Enum CheckpointError 

pub enum CheckpointError {
    Io(Error),
    Parse(Error),
    HashMismatch {
        expected: String,
        actual: String,
    },
    ContentMismatch {
        expected: String,
        actual: String,
    },
    AddressMismatch {
        expected: String,
        found: String,
    },
}

A checkpoint load/verify failure.

Variants

Io(Error)

Parse(Error)

HashMismatch

The stored state_hash does not recompute from the stored state — tampering, corruption, or a fold-determinism bug. Never fold it.

Fields

expected: String

actual: String

ContentMismatch

The stored checkpoint_hash does not recompute from the whole record — a tampered frontier/scopes (or a forged address). Never fold or anchor on it.

Fields

expected: String

actual: String

AddressMismatch

The file’s name is not the record’s content address — a renamed, swapped, or wrongly-stored checkpoint file.

Fields

expected: String

found: String

Trait Implementations

impl Debug for CheckpointError

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

Formats the value using the given formatter.

impl Display for CheckpointError

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

Formats the value using the given formatter.

impl Error for CheckpointError

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<CheckpointError> for SessionError

fn from(e: CheckpointError) -> Self

Converts to this type from the input type.
