Implementations

impl DeviceManagerSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DeviceManagerEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn format( &self, key: &[u8], slot: u8, ___deadline: MonotonicInstant, ) -> Result<i32, Error>

Formats the device, destroying any previously-secured data. A new data key is generated and wrapped with the provided key into key slot slot, Returns ZX_ERR_BAD_STATE if the device is not currently sealed. Returns ZX_OK on success.

pub fn unseal( &self, key: &[u8], slot: u8, ___deadline: MonotonicInstant, ) -> Result<i32, Error>

Attempts to unseal the device by using the provided master key to unwrap the data key wrapped in the specified key slot. If the key provided was the correct key for this slot, then the device node responding to this protocol will create an unsealed zxcrypt device as a child of itself in the device tree before returning success. Returns ZX_ERR_INVALID_ARGS if slot is invalid. Returns ZX_ERR_BAD_STATE and keeps the device open if the device is already unsealed. Returns other errors if operations on the underlying block device return errors. Returns ZX_OK on success.

pub fn seal(&self, ___deadline: MonotonicInstant) -> Result<i32, Error>

Seals the device, causing any previously-created child zxcrypt Device to be removed some time later. (Someday we’d like this to only return once the unsealed child device is removed, but that’s not straightforward today.) Returns ZX_ERR_BAD_STATE if the device is already sealed. Returns ZX_OK on success.

pub fn shred(&self, ___deadline: MonotonicInstant) -> Result<i32, Error>

Shreds the device, permanently overwriting the keys that would allow Unseal()ing the device again in the future. This call does not impact the current sealed/unsealed state of the device – if currently unsealed, the device will remain in that state until Seal() is called or the device is unbound. Returns ZX_OK on success. Returns other errors if operations on the underlying block device return errors.
