Enum RestoreError 

pub enum RestoreError {
    SnapshotMismatch(String),
    ComponentRestoreFailed {
        type_name: String,
        source: RestoreError,
    },
    SpecVersionMismatch {
        got: u32,
        expected: u32,
    },
}

Errors surfaced by Node::restore (the public surface arrives in the commit that lands src/node.rs).

Variants

SnapshotMismatch(String)

Snapshot-level invariant violation (incarnation mismatch, component table mismatch, graph not found, etc.).

ComponentRestoreFailed

One of the snapshotted components failed to deserialize via its registered RestoreFn.

Fields

type_name: String

ConcreteComponent::TYPE_NAME of the failing component.

source: RestoreError

The per-component error.

SpecVersionMismatch

Snapshot’s spec_version doesn’t match the live Node’s CURRENT_SNAPSHOT_SPEC_VERSION. Bumps to the spec version happen when the FrameworkSnapshot shape changes in a way older code cannot soundly restore.

Fields

got: u32

Version stamped on the snapshot.

expected: u32

Version this build supports.

Trait Implementations

impl Debug for RestoreError

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

Formats the value using the given formatter.

impl Display for RestoreError

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

Formats the value using the given formatter.

impl Error for RestoreError

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.
