Struct StaticKeyProvider 

pub struct StaticKeyProvider { /* private fields */ }

A fixed-key provider. Suitable for a local/self-hosted developer who derives a 32-byte key from their passphrase (e.g. Argon2id) and holds it for the session. cold() models a locked vault for tests and for “no key yet” states.

Implementations

impl StaticKeyProvider

pub fn new(key: [u8; 32]) -> Self

A warm provider that always yields key.

pub fn cold() -> Self

A cold provider that always returns CryptoError::Cold.

fn clone(&self) -> StaticKeyProvider

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl KeyProvider for StaticKeyProvider

fn vault_key(&self) -> Result<Zeroizing<[u8; 32]>, CryptoError>

The 32-byte vault key, or CryptoError::Cold if the vault is locked.
