Struct FveMetadata 

pub struct FveMetadata {
    pub encryption_method: u16,
    pub volume_guid: [u8; 16],
    pub creation_time: u64,
    pub entries: Vec<MetadataEntry>,
    pub encrypted_volume_size: u64,
    pub volume_header_offset: u64,
    pub volume_header_size: u64,
    pub metadata_offsets: [u64; 3],
    pub metadata_size: u32,
}

A parsed FVE metadata block: cipher, identity, and the entry array, plus the block-header fields the read path needs (encrypted size and the relocated volume-header region).

Fields

encryption_method: u16

Volume encryption method (metadata header offset 36).

volume_guid: [u8; 16]

Volume identifier GUID (metadata header offset 16).

creation_time: u64

Volume creation time as a Windows FILETIME (metadata header offset 40).

entries: Vec<MetadataEntry>

The metadata entries.

encrypted_volume_size: u64

Number of still-encrypted bytes from the front (block header, v2 offset 16). Zero means “whole volume”.

volume_header_offset: u64

Byte offset where the original volume header is stored, relocated.

volume_header_size: u64

Size in bytes of the relocated volume-header region.

metadata_offsets: [u64; 3]

Byte offsets of the three metadata blocks (read back as zeros).

metadata_size: u32

Size of the metadata region (metadata header offset 0).

Implementations

impl FveMetadata

pub fn parse(block: &[u8], bytes_per_sector: u16) -> Option<FveMetadata>

Parse an FVE metadata block from bytes beginning at its block header.

Returns None when the -FVE-FS- block-header signature is absent, so the caller can try the next candidate block offset.

pub fn vmk_entries(&self) -> impl Iterator<Item = &MetadataEntry>

Iterate the VMK protector entries.

pub fn protector_types(&self) -> Vec<u16>

The key-protection types present, in metadata order.

pub fn fvek_entry(&self) -> Option<&MetadataEntry>

The top-level FVEK entry (an AES-CCM encrypted key wrapped by the VMK).

Trait Implementations

impl Clone for FveMetadata

fn clone(&self) -> FveMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FveMetadata

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

Formats the value using the given formatter.
