Struct ObjectHeader 

pub struct ObjectHeader {
    pub version: u8,
    pub messages: Vec<HdfMessage>,
    pub reference_count: u32,
    pub modification_time: Option<u32>,
}

Parsed object header with all its messages.

Fields

version: u8

Object header format version (1 or 2).

messages: Vec<HdfMessage>

All parsed header messages, collected from every chunk.

reference_count: u32

Object reference count.

modification_time: Option<u32>

Modification time in seconds since the UNIX epoch (v2 only, when the “times stored” flag is set).

Implementations

impl ObjectHeader

pub fn parse_at( data: &[u8], address: u64, offset_size: u8, length_size: u8, ) -> Result<Self>

Parse an object header at the given absolute file address.

data is the entire file mapped into memory, address is the byte offset where the object header starts, and offset_size / length_size come from the superblock.

pub fn resolve_shared_messages( &mut self, data: &[u8], offset_size: u8, length_size: u8, ) -> Result<()>

Resolve shared messages by following references to other object headers.

For SharedInOhdr, the referenced object header is parsed and the first matching message type is extracted. SharedInSohm returns an error (rare).

Trait Implementations

impl Clone for ObjectHeader

fn clone(&self) -> ObjectHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectHeader

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

Formats the value using the given formatter.
