Enum RestoreError 

#[non_exhaustive]
pub enum RestoreError {
    AlreadyRestored,
    Conflict(Vec<ChannelId>),
    Invariant(&'static str),
}

Restore-specific failure modes surfaced via crate::Error::Restore. Every variant is reported before any store mutation — a precondition error is exactly equivalent to never having called restore. Store I/O failures mid-restore propagate as their underlying crate::Error variant instead.

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.

AlreadyRestored

A user-secret snapshot already exists for the protocol’s secret_id. The application must clear it before retrying.

Conflict(Vec<ChannelId>)

One or more channels already live at canonical helper or replica ids carried by the recovered Secret. The contained list enumerates the collisions; the application clears them through its own store wrappers and retries.

Invariant(&'static str)

The recovered Secret is internally inconsistent. Only reachable when a Secret was hand-crafted — library-produced ones always satisfy the invariants (rebuilt inside the sharing handler during a start(ProtectSecret) round).

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, __formatter: &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.

impl From<RestoreError> for Error

fn from(source: RestoreError) -> Self

Converts to this type from the input type.
