Struct WorkerCapabilities 

pub struct WorkerCapabilities {
    pub protocol_version: u64,
    pub features: BTreeSet<String>,
    pub cpex_version: Option<String>,
}

What a worker reported it can do, from the spawn-time handshake.

An empty feature set is a valid, meaningful answer: it is what an old worker that does not know the handshake reports, and it must make the host fail closed rather than assume support.

Fields

protocol_version: u64

The worker’s declared protocol version, or 0 if it reported none.

features: BTreeSet<String>

Feature names the worker claims to implement.

cpex_version: Option<String>

The installed cpex distribution version, for diagnostics only.

Never gated on: two builds shipped as 0.1.2 with different worker protocols, so the version string cannot carry a decision. features is the contract.

Implementations

impl WorkerCapabilities

pub fn none() -> Self
