Struct Annotations 

pub struct Annotations(/* private fields */);

Key-sorted, free-form resource metadata.

Annotations are kept distinct from labels because they are descriptive data, not selectors used for routing or filtering.

Implementations

impl Annotations

pub fn new() -> Self

Creates an empty annotation map.

pub fn len(&self) -> usize

Returns the number of annotations.

pub fn is_empty(&self) -> bool

Returns whether the map is empty.

pub fn insert<K, V>(&mut self, key: K, value: V) -> &mut Self

where K: Into<String>, V: Into<String>,

Inserts or replaces an annotation.

pub fn get(&self, key: &str) -> Option<&str>

Returns an annotation value.

pub fn iter(&self) -> impl Iterator<Item = (&str, &str)>

Iterates over annotations in key order.

pub fn validate(&self) -> ModelResult<()>

Validates annotation keys and total size.

Annotation values remain arbitrary UTF-8 strings.

Errors

Returns ModelError::Invalid for an invalid key or when key and value bytes exceed 256 KiB in total.

Trait Implementations

impl Clone for Annotations

fn clone(&self) -> Annotations

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Annotations

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

Formats the value using the given formatter.

impl Default for Annotations

fn default() -> Annotations

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Annotations

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Annotations

impl JsonSchema for Annotations

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Annotations

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Annotations

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
