Enum mz_catalog::durable::FenceError

pub enum FenceError {
    DeployGeneration {
        current_generation: u64,
        fence_generation: u64,
    },
    Epoch {
        current_epoch: Epoch,
        fence_epoch: Epoch,
    },
    MigrationUpper {
        expected_upper: Timestamp,
        actual_upper: Timestamp,
    },
}

An error that indicates the durable catalog has been fenced.

The order of this enum indicates the most information to the least information.

Variants

DeployGeneration

This instance was fenced by another instance with a higher deployment generation. This necessarily means that the other instance also had a higher epoch. The instance that fenced us believes that they are from a later generation than us.

Fields

current_generation: u64

fence_generation: u64

Epoch

This instance was fenced by another instance with a higher epoch. The instance that fenced us may or may not be from a later generation than us, we were unable to determine.

Fields

current_epoch: Epoch

fence_epoch: Epoch

MigrationUpper

This instance was fenced while writing to the migration shard during 0dt builtin table migrations.

Fields

expected_upper: Timestamp

actual_upper: Timestamp

Implementations

impl FenceError

pub fn migration(err: UpperMismatch<Timestamp>) -> Self

Trait Implementations

impl Clone for FenceError

fn clone(&self) -> FenceError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FenceError

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

Formats the value using the given formatter.

impl Display for FenceError

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

Formats the value using the given formatter.

impl Error for FenceError

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<FenceError> for CatalogError

fn from(err: FenceError) -> Self

Converts to this type from the input type.

impl From<FenceError> for CompareAndAppendError

fn from(source: FenceError) -> Self

Converts to this type from the input type.

impl From<FenceError> for DurableCatalogError

fn from(source: FenceError) -> Self

Converts to this type from the input type.

impl Ord for FenceError

fn cmp(&self, other: &FenceError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FenceError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FenceError

fn partial_cmp(&self, other: &FenceError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
