Enum mz_storage::healthcheck::HealthStatusUpdate

pub enum HealthStatusUpdate {
    Running,
    Stalled {
        error: String,
        hint: Option<String>,
        should_halt: bool,
    },
    Ceased {
        error: String,
    },
}

NB: we derive Ord here, so the enum order matters. Generally, statuses later in the list take precedence over earlier ones: so if one worker is stalled, we’ll consider the entire source to be stalled.

Implementations

impl HealthStatusUpdate

pub(crate) fn running() -> Self

Generates a running HealthStatusUpdate.

pub(crate) fn stalled(error: String, hint: Option<String>) -> Self

Generates a non-halting HealthStatusUpdate with update.

pub(crate) fn halting(error: String, hint: Option<String>) -> Self

Generates a halting HealthStatusUpdate with update.

pub(crate) fn should_halt(&self) -> bool

Whether or not we should halt the dataflow instances and restart it.

Trait Implementations

impl Clone for HealthStatusUpdate

fn clone(&self) -> HealthStatusUpdate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HealthStatusUpdate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HealthStatusUpdate

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for HealthStatusUpdate

fn cmp(&self, other: &HealthStatusUpdate) -> 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 HealthStatusUpdate

fn eq(&self, other: &HealthStatusUpdate) -> 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 HealthStatusUpdate

fn partial_cmp(&self, other: &HealthStatusUpdate) -> 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.

impl Serialize for HealthStatusUpdate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
