Module capability 

Uniform capability model (act:core §3.1).

One envelope (CapabilityRequest) describes every capability class — filesystem, http, sockets, inter-component, semantic, or plugin-provided. The per-class difference lives in constraints (a provider-defined, opaque-at-this-layer JSON predicate), not in separate Rust types.

Structs

Capabilities

Capability declarations from the std.capabilities map in act:component. Serializes transparently as a CBOR/JSON map keyed by capability id.

CapabilityRequest

Uniform capability request — one entry per capability class in the act:component std.capabilities map.

Type Aliases

Constraint

A provider-defined constraint predicate, opaque at the act:core layer. Each capability provider supplies the JSON Schema that validates it. E.g. filesystem { "path": "...", "mode": "ro" }, http { "host": "..." }, a semantic class { "database": "staging_*" }.
