Struct WorkerCapabilities 

pub struct WorkerCapabilities {

    pub rustc_version: Option<String>,
    pub bun_version: Option<String>,
    pub node_version: Option<String>,
    pub npm_version: Option<String>,
    pub num_cpus: Option<u32>,
    pub load_avg_1: Option<f64>,
    pub load_avg_5: Option<f64>,
    pub load_avg_15: Option<f64>,
    pub disk_free_gb: Option<f64>,
    pub disk_total_gb: Option<f64>,
    pub projects_root_ok: Option<bool>,
    pub projects_root_issue: Option<String>,
    pub projects_root_checked_at_unix_ms: Option<i64>,
}

Runtime capabilities detected on a worker.

These are probed during health checks and cached for routing decisions. Commands requiring specific runtimes (e.g., bun test) can be routed only to workers with the corresponding capability.

Fields

rustc_version: Option<String>

Rust compiler version (from rustc --version).

bun_version: Option<String>

Bun runtime version (from bun --version).

node_version: Option<String>

Node.js version (from node --version).

npm_version: Option<String>

npm version (from npm --version).

num_cpus: Option<u32>

Number of CPU cores on the worker.

load_avg_1: Option<f64>

1-minute load average.

load_avg_5: Option<f64>

5-minute load average.

load_avg_15: Option<f64>

15-minute load average.

disk_free_gb: Option<f64>

Free disk space in GB (on /tmp or build directory).

disk_total_gb: Option<f64>

Total disk space in GB.

projects_root_ok: Option<bool>

Canonical path-topology preflight status (/data/projects + /dp alias).

Some(false) indicates a hard preflight failure that should exclude this worker from remote scheduling until a subsequent successful revalidation.

projects_root_issue: Option<String>

Machine-readable failure reason for path-topology preflight.

projects_root_checked_at_unix_ms: Option<i64>

Unix timestamp (ms) when topology preflight last executed.

Implementations

impl WorkerCapabilities

pub fn new() -> Self

Create new empty capabilities.

pub fn mock_with_rust() -> Self

Create mock capabilities with Rust installed.

Used by mock transport to simulate a worker with Rust toolchain.

pub fn has_bun(&self) -> bool

Check if this worker has Bun installed.

pub fn has_node(&self) -> bool

Check if this worker has Node.js installed.

pub fn has_rust(&self) -> bool

Check if this worker has Rust installed.

pub fn load_per_core(&self) -> Option<f64>

Calculate load per core (1-minute load average / num_cpus). Returns None if metrics are unavailable.

pub fn is_high_load(&self, max_load_per_core: f64) -> Option<bool>

Check if worker has high load (exceeds threshold). Returns None if metrics unavailable (fail-open).

pub fn is_low_disk(&self, min_free_gb: f64) -> Option<bool>

Check if worker has low disk space (below threshold). Returns None if metrics unavailable (fail-open).

pub fn is_topology_healthy(&self) -> Option<bool>

Check if canonical path-topology preflight is healthy.

Returns None when probe data is unavailable (fail-open behavior).

Trait Implementations

impl Clone for WorkerCapabilities

fn clone(&self) -> WorkerCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorkerCapabilities

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

Formats the value using the given formatter.

impl Default for WorkerCapabilities

fn default() -> WorkerCapabilities

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WorkerCapabilities

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for WorkerCapabilities

fn schema_name() -> String

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 is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Serialize for WorkerCapabilities

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
