Struct MeasurementMgr 

pub struct MeasurementMgr { /* private fields */ }

Responsible for storing all software components measurements and performing the read_measurement and extend_measurement functions.

Implementations

impl MeasurementMgr

pub fn init( boot_measurements: Vec<BootMeasurement>, ) -> Result<MeasurementMgr, MeasurementError>

Initializes with BootMeasurements repacked and stores as Measurement slots.

pub fn read_measurement( &self, slot_id: usize, ) -> Result<(&Measurement, bool), MeasurementError>

Returns measurement metadata, value and locked attribute from given slot_id. Returns MeasurementError::InvalidArgument, when slot_id is out of bounds. Returns MeasurementError::DoesNotExist, when is not populated.

pub fn extend_measurement( &mut self, slot_id: usize, measurement: Measurement, lock: bool, ) -> Result<(), MeasurementError>

Extends measurement with updated metadata, value and locked attribute in given slot_id. Returns MeasurementError::InvalidArgument, when slot_id is out of bounds. Returns MeasurementError::BadState, when measurement is locked. Returns MeasurementError::NotPermitted, when measurements signer id’s and algorithm do not match.

Trait Implementations

impl Debug for MeasurementMgr

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
