Struct LabelSet 

#[non_exhaustive]
pub struct LabelSet {
    pub labels: HashMap<String, String>,
    /* private fields */
}

Message representing label set.

• A label is a key value pair set for a VM.
• A LabelSet is a set of labels.
• Labels within a LabelSet are ANDed. In other words, a LabelSet is applicable for a VM only if it matches all the labels in the LabelSet.
• Example: A LabelSet with 2 labels: env=prod and type=webserver will only be applicable for those VMs with both labels present.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

labels: HashMap<String, String>

Labels are identified by key/value pairs in this map. A VM should contain all the key/value pairs specified in this map to be selected.

Implementations

impl LabelSet

pub fn new() -> Self

Creates a new default instance.

pub fn set_labels<T, K, V>(self, v: T) -> Self

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Sets the value of labels.

Example

let x = LabelSet::new().set_labels([
    ("key0", "abc"),
    ("key1", "xyz"),
]);
