Enum MigrateError

    UnknownMigration(String),
    WrongVersion {
        actual: String,
        expected: String,
    },
    Unmapped(Vec<BTreeSet<String>>),

    Append(AppendError),
}

Why a migration or fork was refused.

Variants

UnknownMigration(String)

No migration with that IRI is declared.

WrongVersion

The actor does not run the migration’s source version.

Fields

actual: String

The version the actor runs.

expected: String

The migration’s source version.

Unmapped(Vec<BTreeSet<String>>)

Reachable configurations the migration does not map.

TooManyConfigurations(usize)

Too many reachable configurations to check.

TransformFailed(String)

The datamodel transform failed; nothing was appended.

Activation(ActivationError)

The actor could not be activated.

NotStarted

The actor has no state yet (empty journal).

Exists(Address)

The target actor of a fork already has a journal.

Append(AppendError)

The append failed.

Trait Implementations

impl Clone for MigrateError

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 MigrateError

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

Formats the value using the given formatter.

impl Display for MigrateError

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

Formats the value using the given formatter.

impl Error for MigrateError

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 PartialEq for MigrateError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
