Struct TdxFeatures0 

pub struct TdxFeatures0(/* private fields */);

The global-scope TDX_FEATURES0 metadata field, enumerating optional TDX module features. Read by the guest via TDG.SYS.RD (TdCallLeaf::SYS_RD).

Only the bits relevant to hardware-bound sealing are modeled here; the remaining bits are documented by the Intel TDX Module ABI specification.

Implementations

impl TdxFeatures0

Trait Implementations

impl Clone for TdxFeatures0

fn clone(&self) -> TdxFeatures0

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TdxFeatures0

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

Formats the value using the given formatter.

impl Default for TdxFeatures0

fn default() -> Self

Returns the “default value” for a type.

impl From<TdxFeatures0> for u64

fn from(v: TdxFeatures0) -> u64

Converts to this type from the input type.

impl From<u64> for TdxFeatures0

fn from(v: u64) -> Self

Converts to this type from the input type.

impl PartialEq for TdxFeatures0

fn eq(&self, other: &TdxFeatures0) -> 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.
