Crate walletkit_db 

Encrypted on-device storage primitives for WalletKit.

The crate provides building blocks shared by walletkit-core::storage and sibling SDKs (e.g. OrbKit’s OrbPcpStore):

• Vault — encrypted-database wrapper around a caller-supplied schema, exposing the underlying walletkit_sqlite::Connection.
• blobs — content-addressed blob storage (ensure_schema, put, get), ContentId, and compute_content_id.
• init_or_open_envelope_key — sealed intermediate key persisted via AtomicBlobStore.
• Lock / LockGuard — cross-process exclusive lock (flock / LockFileEx native, no-op on WASM).
• Keystore / AtomicBlobStore — plain-Rust trait surface for consumer-supplied platform integrations. Consumers that need FFI define their own annotated traits and adapt to these.

Consumers own their schemas, FFI surfaces, and storage policy on top of these primitives.

Re-exports

pub use blobs::compute_content_id;

pub use blobs::ContentId;

Modules

blobs

Content-addressed blob storage shared across consumer vaults.

Structs

Lock

File-backed cross-process exclusive lock. See the module docs for what it’s for (and what it isn’t).

LockGuard

Guard that holds an exclusive lock for its lifetime.

Vault

Open encrypted database wrapper.

Enums

StoreError

Errors raised by the storage primitives (vault, blobs, envelope, lock).

Traits

AtomicBlobStore

Atomic blob store for small binary files (e.g. sealed key envelopes).

Keystore

Device keystore for sealing and opening secrets under a device-bound key.

Functions

init_or_open_envelope_key

Initialize or open the envelope-sealed intermediate key.

Type Aliases

StoreResult

Result alias for StoreError.
