Skip to main content Module types Copy item path Source ActError Error type mapping to ACT tool-error. ComponentInfo Component metadata stored in the act:component WASM custom section (CBOR-encoded). FilesystemAllow One path × mode entry in a [std.capabilities."wasi:filesystem"].allow array.
Both fields are required. FilesystemMount One entry in params.mounts of the wasi:filesystem capability. HttpAllow One entry in a [std.capabilities."wasi:http"].allow array. Metadata Key → value metadata, stored as JSON values internally. SocketsAllow One entry in a [std.capabilities."wasi:sockets"].allow array. StdComponentInfo Well-known component metadata under the std namespace. StdCredential One credential a component declares it expects (design §4.3). Descriptive,
not restrictive: the boundary is the profile, and a component asking for an
undeclared key is refused by nothing. StdCredentialField One field of a declared credential. field_type binds the encoding and how
act login acquires it (design §3.2). FsMode Filesystem access mode a component declares for a path. LocalizedString A localizable text value, matching the WIT localized-string variant. MountType Mount kind for a wasi:filesystem params.mounts entry (topology only). SocketProtocol Raw socket protocol — TCP or UDP. validate_mounts Validate a list of mounts. Rules are independent of the constraint set
(cross-checks like the drift lint live in act-build). Returns the first
violation as a human-readable string. ActResult Result type for ACT operations.
