Struct State 

pub struct State {
    pub oci_version: String,
    pub id: String,
    pub status: ContainerStatus,
    pub pid: Option<i32>,
    pub bundle: PathBuf,
    pub annotations: Option<HashMap<String, String>>,
    pub created: Option<DateTime<Utc>>,
    pub creator: Option<u32>,
    pub use_systemd: bool,
    pub clean_up_intel_rdt_subdirectory: Option<bool>,
}

Stores the state information of the container

Fields

oci_version: String

id: String

status: ContainerStatus

pid: Option<i32>

bundle: PathBuf

annotations: Option<HashMap<String, String>>

created: Option<DateTime<Utc>>

creator: Option<u32>

Implementations

impl State

pub fn new( container_id: &str, status: ContainerStatus, pid: Option<i32>, bundle: PathBuf, ) -> Self

pub fn save(&self, container_root: &Path) -> Result<(), StateError>

pub fn load(container_root: &Path) -> Result<Self, StateError>

pub fn file_path(container_root: &Path) -> PathBuf

Returns the path to the state JSON file for the provided container_root.

let container_root = Path::new("/var/run/containers/container");
let state_file = State::file_path(&container_root);
assert_eq!(state_file.to_str(), Some("/var/run/containers/container/state.json"));

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for State

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

Formats the value using the given formatter.

impl Default for State

fn default() -> State

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for State

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for State

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&State> for State

Convert internal State to OCI-compliant State (by reference, cloning necessary fields).

Based on runc’s implementation: https://github.com/opencontainers/runc/blob/v2.2.1/libcontainer/container_linux.go#L961

type Error = StateConversionError

The type returned in the event of a conversion error.

fn try_from(state: &State) -> Result<Self, Self::Error>

Performs the conversion.
