Struct Vault 

pub struct Vault { /* private fields */ }

The mapping vault that maintains entity<->token consistency.

Implementations

impl Vault

pub fn open(path: &str, key: Vec<u8>) -> Result<Self>

Create or load a vault from the given path.

pub fn ephemeral() -> Self

Create an ephemeral (in-memory only) vault for testing.

pub fn set_resolver(&mut self, resolver: EntityResolver)

Configure the fuzzy entity resolver on this vault.

pub fn get_or_create( &mut self, original: &str, category: &EntityCategory, ) -> PseudoToken

Get or create a pseudo-token for the given original value.

If a fuzzy entity resolver is configured, checks for similar existing entries before creating a new token. This merges variant spellings (e.g., “Rishi” and “Rishikesh”) to the same token.

pub fn lookup(&self, token: &str) -> Option<&str>

Look up the original value for a pseudo-token (for rehydration).

pub fn reverse_mappings(&self) -> HashMap<String, String>

Get all reverse mappings (for rehydration).

pub fn save(&self) -> Result<()>

Save the vault to disk (AES-256-GCM encrypted).

pub fn stats(&self) -> VaultStats

Get vault statistics (safe to expose — no sensitive data).
