Enum Hierarchy 

pub enum Hierarchy {
    Owner,
    Platform,
    Endorsement,
}

A TPM 2.0 hierarchy. Maps to the three persistent hierarchies defined by the TPM 2.0 specification: owner, platform, and endorsement. The parent key under which Confium wraps its sealed objects lives in one of these.

Wire form is the lowercase ASCII name (see Hierarchy::from_wire).

Variants

Owner

The owner hierarchy (TPM_RH_OWNER). Default for Confium; parent key authorisation usually uses an empty auth value.

Platform

The platform hierarchy (TPM_RH_PLATFORM). Controlled by the platform firmware; clears on every reboot.

Endorsement

The endorsement hierarchy (TPM_RH_ENDORSEMENT). Used for privacy-sensitive operations (attestation, EK-derived keys).

Implementations

impl Hierarchy

pub fn from_wire(value: &str) -> Result<Self>

Decode the wire value used by the FFI / options map. Accepts the case-insensitive ASCII name; unknown values map to [Error::Wrapped].

pub fn as_wire(self) -> &'static str

The wire name this hierarchy serialises to (lowercase ASCII).

Trait Implementations

impl Clone for Hierarchy

fn clone(&self) -> Hierarchy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Hierarchy

impl Debug for Hierarchy

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

Formats the value using the given formatter.

impl Display for Hierarchy

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

Formats the value using the given formatter.

impl Eq for Hierarchy

impl Hash for Hierarchy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Hierarchy

fn eq(&self, other: &Hierarchy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
