Struct LinuxKeyutilsStore 

pub struct LinuxKeyutilsStore { /* private fields */ }

A second, independently-selectable KeyStore backend — proof that the trait boundary is genuinely overridable, not merely declared to be: the kernel’s own keyutils facility, no D-Bus/secret-service daemon required. This is what KeyringStore’s underlying keyring dependency itself recommends for headless Linux (containers, CI, a sandboxed dev box with no gnome-keyring/kwalletd running) — see linux-keyutils-keyring-store’s own module doc, which states this outright.

Deliberately does NOT go through keyring’s own v1::Entry/ keyring_core::set_default_store (a process-global) — doing so would silently fight KeyringStore’s own default-store selection if both were ever constructed in the same process, with whichever initializes first winning. Instead this holds its own Store instance and asks it directly for a credential via CredentialStoreApi::build, which never touches the global default at all.

Trait Implementations

impl KeyStore for LinuxKeyutilsStore

Available on Linux only.

fn save_key(&self, key: &[u8]) -> Result<(), KeyStoreError>

Persist key, overwriting any value already stored under this store’s identity.

fn load_key(&self) -> Result<Zeroizing<Vec<u8>>, KeyStoreError>

Retrieve a previously-save_keyd key. KeyStoreError::NotFound if nothing has been stored yet.

fn delete_key(&self) -> Result<(), KeyStoreError>

Remove a previously-stored key, if any. Not required before a save_key (which overwrites), only for deliberately forgetting an identity.
