Struct optee_utee::object::ObjectInfo

pub struct ObjectInfo { /* fields omitted */ }

Represent the characteristics of an object. This info can be returned by TransientObject function info or PersistentObject function info.

Implementations

impl ObjectInfo

pub fn from_raw(raw: TEE_ObjectInfo) -> Self

Return an ObjectInfo struct based on the raw structrure TEE_ObjectInfo. The raw structure contains following fields:

1. objectType: The parameter represents one of the TransientObjectType.
2. objectSize: The current size in bits of the object as determined by its attributes. This will always be less than or equal to maxObjectSize. Set to 0 for uninitialized and data only objects.
3. maxObjectSize: The maximum objectSize which this object can represent. 3.1) For a PersistentObject, set to objectSize. 3.2) For a TransientObject, set to the parameter maxObjectSize passed to allocate.
4. objectUsage: A bit vector of UsageFlag.
5. dataSize: 5.1) For a PersistentObject, set to the current size of the data associated with the object. 5.2) For a TransientObject, always set to 0.
6. dataPosition: 6.1) For a PersistentObject, set to the current position in the data for this handle. Data positions for different handles on the same object may differ. 6.2) For a TransientObject, set to 0.
7. handleFlags: A bit vector containing one or more HandleFlag or DataFlag.

pub fn data_size(&self) -> usize

Return the dataSize field of the raw structrure TEE_ObjectInfo.

pub fn object_size(&self) -> usize

Return the objectSize field of the raw structrure TEE_ObjectInfo.
