Struct AutoApplyUpgrader

Source

pub struct AutoApplyUpgrader { /* private fields */ }

Expand description

Auto-apply upgrader with archive support.

Implementations§

Source §

impl AutoApplyUpgrader

Source

pub fn new() -> Self

Create a new auto-apply upgrader.

Source

pub fn with_binary_cache(self, cache: BinaryCache) -> Self

Configure a shared binary cache for downloaded upgrades.

When set, apply_upgrade will check the cache before downloading and store freshly verified binaries so other nodes can reuse them.

Source

pub fn with_stop_on_upgrade(self, stop: bool) -> Self

Configure the upgrader to exit cleanly instead of spawning a new process.

When enabled, the node exits after applying an upgrade, relying on an external service manager (systemd, launchd, Windows Service) to restart it.

Source

pub fn current_version(&self) -> &Version

Get the current version.

Source

pub fn current_binary_path() -> Result<PathBuf>

Get the path to the currently running binary.

On Linux, /proc/self/exe may have a " (deleted)" suffix when the on-disk binary has been replaced by another node’s upgrade. This function strips that suffix so that backup creation, binary replacement, and restart all target the correct on-disk path.

§Errors

Returns an error if the binary path cannot be determined.

Source

pub async fn apply_upgrade(&self, info: &UpgradeInfo) -> Result<UpgradeResult>

Perform the complete auto-apply upgrade workflow.

§Arguments

info - Upgrade information from the monitor

§Returns

Returns UpgradeResult::Success and triggers a restart on success. Returns UpgradeResult::RolledBack if any step fails.

§Errors

Returns an error only for critical failures where rollback also fails.
