Struct kube_core::object::ObjectList

pub struct ObjectList<T>
where T: Clone,
{ pub types: TypeMeta, pub metadata: ListMeta, pub items: Vec<T>, }
Expand description

A generic Kubernetes object list

This is used instead of a full struct for DeploymentList, PodList, etc. Kubernetes’ API always seem to expose list structs in this manner.

Note that this is only used internally within reflectors and informers, and is generally produced from list/watch/delete collection queries on an Resource.

This is almost equivalent to k8s_openapi::List<T>, but iterable.

Fields§

§types: TypeMeta

The type fields, always present

§metadata: ListMeta

ListMeta - only really used for its resourceVersion

See ListMeta

§items: Vec<T>

The items we are actually interested in. In practice; T := Resource<T,U>.

Implementations§

source§

impl<T: Clone> ObjectList<T>

source

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

iter returns an Iterator over the elements of this ObjectList

§Example
use kube::api::{ListMeta, ObjectList, TypeMeta};
use k8s_openapi::api::core::v1::Pod;

let types: TypeMeta = TypeMeta::list::<Pod>();
let metadata: ListMeta = Default::default();
let items = vec![1, 2, 3];

let first = objectlist.iter().next();
println!("First element: {:?}", first); // prints "First element: Some(1)"
source

pub fn iter_mut(&mut self) -> impl Iterator<Item = &mut T>

iter_mut returns an Iterator of mutable references to the elements of this ObjectList

§Example
use kube::api::{ListMeta, ObjectList, TypeMeta};
use k8s_openapi::api::core::v1::Pod;

let types: TypeMeta = TypeMeta::list::<Pod>();
let metadata: ListMeta = Default::default();
let items = vec![1, 2, 3];

let mut first = objectlist.iter_mut().next();

// Reassign the value in first
if let Some(elem) = first {
    *elem = 2;
    println!("First element: {:?}", elem); // prints "First element: 2"
}
