l1fe-weave-core · storage::lens
Source declarations, signatures and documentation for storage::lens.
Reviewed implementation boundary: Some core wrappers derive transport keys from DID strings. Do not infer secret key custody or authenticated peers from a supplied DID string; inspect the chosen wrapper and transport configuration. See /libraries/weave-core/overview.
