Hardware and deployment metadata for a node.

Fields

cores: u32

Number of CPU cores available.

memory_bytes: u64

Total memory in bytes.

failure_domain: Option<String>

Failure domain (e.g., rack, zone, region).

tags: HashMap<String, String>

Arbitrary key-value tags.

owned_partitions: Vec<u32>

Partitions currently owned by this node.

version: String

LaminarDB version string.

Trait Implementations

impl Archive for NodeMetadata

where u32: Archive, u64: Archive, Option<String>: Archive, HashMap<String, String>: Archive, Vec<u32>: Archive, String: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedNodeMetadata

The archived representation of this type.

type Resolver = NodeMetadataResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for NodeMetadata

fn clone(&self) -> NodeMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeMetadata

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

Formats the value using the given formatter.

impl Default for NodeMetadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NodeMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<NodeMetadata, __D> for Archived<NodeMetadata>

where u32: Archive, <u32 as Archive>::Archived: Deserialize<u32, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, Option<String>: Archive, <Option<String> as Archive>::Archived: Deserialize<Option<String>, __D>, HashMap<String, String>: Archive, <HashMap<String, String> as Archive>::Archived: Deserialize<HashMap<String, String>, __D>, Vec<u32>: Archive, <Vec<u32> as Archive>::Archived: Deserialize<Vec<u32>, __D>, String: Archive, <String as Archive>::Archived: Deserialize<String, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<NodeMetadata, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<__S: Fallible + ?Sized> Serialize<__S> for NodeMetadata

where u32: Serialize<__S>, u64: Serialize<__S>, Option<String>: Serialize<__S>, HashMap<String, String>: Serialize<__S>, Vec<u32>: Serialize<__S>, String: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for NodeMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
