Struct Metadata 

pub struct Metadata {
    pub name: String,
    pub kind: String,
    pub labels: BTreeSet<String>,
    pub weights: BTreeMap<String, f64>,
    pub annotations: BTreeMap<String, Value>,
    /* private fields */
}

Metadata struct that contains common metadata for any instance.

Fields

name: String

Instance name.

kind: String

Main category of this instance.

labels: BTreeSet<String>

Instance labels.

weights: BTreeMap<String, f64>

Numeric instance weights.

annotations: BTreeMap<String, Value>

Miscellaneous data fields for this instance.

Implementations

impl Metadata

pub fn new( id: Option<Uuid>, name: Option<String>, kind: Option<String>, labels: Option<BTreeSet<String>>, weights: Option<BTreeMap<String, f64>>, annotations: Option<BTreeMap<String, Value>>, ) -> Self

Create a new Meta struct with arguments.

pub fn id(&self) -> &Uuid

The unique ID of this instance.

pub fn set_id(&mut self, value: Option<Uuid>)

Set the unique ID to a custom value (or generate a new one with None). Use with care! References in node and edge stores are NOT updated automatically.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Metadata

fn eq(&self, other: &Metadata) -> 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 Serialize for Metadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
