Struct RuntimeContext 

pub struct RuntimeContext {
    pub environment: Environment,
    pub pod_name: Option<String>,
    pub namespace: Option<String>,
    pub node_name: Option<String>,
    pub container_id: Option<String>,
    pub memory_limit_bytes: Option<u64>,
    pub cpu_quota_cores: Option<f64>,
}

Rich runtime context detected once at startup, immutable after.

Provides all K8s/container metadata in one place. Modules read from this instead of doing their own env var lookups. Detected lazily on first access via runtime_context().

On bare metal, most fields are None — features that read them become no-ops.

Fields

environment: Environment

Detected runtime environment.

pod_name: Option<String>

K8s pod name (from POD_NAME or HOSTNAME env var).

namespace: Option<String>

K8s namespace (from POD_NAMESPACE env var or service account).

node_name: Option<String>

K8s node name (from NODE_NAME env var).

container_id: Option<String>

Container ID (from HOSTNAME in container environments).

memory_limit_bytes: Option<u64>

cgroup memory limit in bytes (None if unlimited or bare metal).

cpu_quota_cores: Option<f64>

cgroup CPU quota in cores (None if unlimited or bare metal).

Implementations

impl RuntimeContext

pub fn detect() -> Self

Detect the full runtime context.

Reads environment variables and filesystem signals. Safe to call on bare metal — fields will be None when not in a container.

pub fn is_kubernetes(&self) -> bool

Convenience: is this running in Kubernetes?

pub fn is_container(&self) -> bool

Convenience: is this running in any container?

pub fn is_bare_metal(&self) -> bool

Convenience: is this bare metal / local dev?

Trait Implementations

impl Clone for RuntimeContext

fn clone(&self) -> RuntimeContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeContext

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

Formats the value using the given formatter.

impl Default for RuntimeContext

fn default() -> Self

Returns the “default value” for a type.
