Struct BootAttestation 

#[repr(C)]
pub struct BootAttestation {
    pub rvf_hash: [u8; 32],
    pub capability_table_hash: [u8; 32],
    pub region_layout_hash: [u8; 32],
    pub boot_timestamp_ns: u64,
    pub boot_sequence: u64,
    pub platform_id: u64,
    pub reserved: [u8; 16],
}

Boot attestation entry recorded as the first witness log entry.

Contains cryptographic hashes of the initial system state for later verification and audit.

Fields

rvf_hash: [u8; 32]

SHA-256 hash of the RVF package that was booted.

capability_table_hash: [u8; 32]

SHA-256 hash of the initial capability table.

region_layout_hash: [u8; 32]

SHA-256 hash of the region layout.

boot_timestamp_ns: u64

Boot timestamp in nanoseconds since UNIX epoch.

boot_sequence: u64

Boot sequence number (for multi-boot detection).

platform_id: u64

Platform identifier.

reserved: [u8; 16]

Reserved for future use.

Implementations

impl BootAttestation

pub const SIZE: usize

Size of boot attestation in bytes.

pub fn new( rvf_hash: [u8; 32], capability_table_hash: [u8; 32], region_layout_hash: [u8; 32], boot_timestamp_ns: u64, ) -> Self

Creates a new boot attestation.

pub fn with_metadata( rvf_hash: [u8; 32], capability_table_hash: [u8; 32], region_layout_hash: [u8; 32], boot_timestamp_ns: u64, boot_sequence: u64, platform_id: u64, ) -> Self

Creates a boot attestation with full metadata.

pub fn hash(&self) -> [u8; 32]

Computes the hash of this attestation.

pub fn to_bytes(&self) -> [u8; 136]

Serializes the attestation to bytes.

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Deserializes an attestation from bytes.

pub fn verify(&self, expected_rvf_hash: &[u8; 32]) -> bool

Verifies that this attestation matches expected values.

Trait Implementations

impl Clone for BootAttestation

fn clone(&self) -> BootAttestation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BootAttestation

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

Formats the value using the given formatter.

impl Default for BootAttestation

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for BootAttestation

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