Struct mz_compute_client::protocol::command::InstanceConfig

pub struct InstanceConfig {
    pub logging: LoggingConfig,
    pub expiration_offset: Option<Duration>,
}

Configuration for a replica, passed with the CreateInstance. Replicas should halt if the controller attempt to reconcile them with different values for anything in this struct.

Fields

logging: LoggingConfig

Specification of introspection logging.

expiration_offset: Option<Duration>

The offset relative to the replica startup at which it should expire. None disables feature.

Implementations

impl InstanceConfig

pub fn compatible_with(&self, other: &InstanceConfig) -> bool

Check if the configuration is compatible with another configuration. This is true iff the logging configuration is equivalent, and the other configuration (non-strictly) strengthens the expiration offset.

We consider a stricter offset compatible, which allows us to strengthen the value without forcing replica restarts. However, it also means that replicas will only pick up the new value after a restart.

Trait Implementations

impl Arbitrary for InstanceConfig

type Parameters = (<LoggingConfig as Arbitrary>::Parameters, <Option<Duration> as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<LoggingConfig as Arbitrary>::Strategy, <Option<Duration> as Arbitrary>::Strategy), fn(_: (LoggingConfig, Option<Duration>)) -> InstanceConfig>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for InstanceConfig

fn clone(&self) -> InstanceConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InstanceConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for InstanceConfig

fn eq(&self, other: &InstanceConfig) -> 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 RustType<ProtoInstanceConfig> for InstanceConfig

fn into_proto(&self) -> ProtoInstanceConfig

Convert a Self into a Proto value.

fn from_proto(proto: ProtoInstanceConfig) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

impl Serialize for InstanceConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
