MetadataEntry

Struct MetadataEntry 

Source
pub struct MetadataEntry {
    pub entry_type: u16,
    pub value_type: u16,
    pub version: u16,
    pub data: Vec<u8>,
}
Expand description

One FVE metadata entry (entry_type, value_type, version, and the raw value data that follows the 8-byte entry header).

Fields§

§entry_type: u16

Entry type (e.g. [ENTRY_TYPE_VMK]).

§value_type: u16

Value type (e.g. [VALUE_TYPE_AES_CCM]).

§version: u16

Entry version (typically 1).

§data: Vec<u8>

The value data following the 8-byte entry header.

Implementations§

Source§

impl MetadataEntry

Source

pub fn parse_sequence(data: &[u8]) -> Vec<MetadataEntry>

Parse a flat sequence of metadata entries from data.

Each entry is size(u16) | entry_type(u16) | value_type(u16) | version(u16) | value_data. Parsing stops on a size below the 8-byte header, an entry that would run past the buffer, or the end of data — never looping forever on a lying size.

Source

pub fn nested(&self, offset: usize) -> Vec<MetadataEntry>

Parse this entry’s value data (from offset) as a nested entry sequence.

Source

pub fn is_vmk(&self) -> bool

Whether this entry is a VMK protector.

Source

pub fn protection_type(&self) -> Option<u16>

The key-protection type of a VMK entry (protector type at value offset 26), or None for a non-VMK entry.
