Struct LabelSelector 

pub struct LabelSelector {
    pub match_labels: Option<BTreeMap<String, String>>,
    pub match_expressions: Option<Vec<LabelSelectorRequirement>>,
}

Label selector to match Kubernetes resources.

A label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects.

Fields

match_labels: Option<BTreeMap<String, String>>

Map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is “key”, the operator is “In”, and the values array contains only “value”. All requirements must be satisfied.

match_expressions: Option<Vec<LabelSelectorRequirement>>

List of label selector requirements. All requirements must be satisfied.

Implementations

impl LabelSelector

pub fn matches(&self, labels: &BTreeMap<String, String>) -> bool

Checks if this label selector matches the given labels.

Returns true if all match requirements are satisfied.

Arguments

• labels - The labels to match against (from metadata.labels)

Examples

use std::collections::BTreeMap;
use bindy::crd::LabelSelector;

let selector = LabelSelector {
    match_labels: Some(BTreeMap::from([
        ("app".to_string(), "podinfo".to_string()),
    ])),
    match_expressions: None,
};

let labels = BTreeMap::from([
    ("app".to_string(), "podinfo".to_string()),
    ("env".to_string(), "dev".to_string()),
]);

assert!(selector.matches(&labels));

Trait Implementations

impl Clone for LabelSelector

fn clone(&self) -> LabelSelector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LabelSelector

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

Formats the value using the given formatter.

impl Default for LabelSelector

fn default() -> LabelSelector

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LabelSelector

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for LabelSelector

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.

where __S: Serializer,

Serialize this value into the given Serde serializer.
