Struct Header 

pub struct Header {
    pub magic: [u8; 4],
    pub version_major: u8,
    pub version_minor: u8,
    pub flags: u16,
}

PARX file header structure (16 bytes total).

Layout:

• bytes 0-3: magic (“PARX”)
• byte 4: version_major
• byte 5: version_minor
• bytes 6-7: flags (little-endian)
• bytes 8-15: reserved

Fields

magic: [u8; 4]

version_major: u8

version_minor: u8

flags: u16

Implementations

impl Header

pub const fn new() -> Self

Create a new header

pub const fn from_bytes(bytes: &[u8; 16]) -> Self

Parse header from bytes.

pub fn to_bytes(&self) -> [u8; 16]

Serialize header to bytes.

pub fn is_magic_valid(&self, expected_magic: [u8; 4]) -> bool

Check if magic matches expected value.

pub const fn is_version_supported(&self) -> bool

Check if version is supported.

pub const fn is_footer_compressed(&self) -> bool

Check if the footer is compressed.

pub const fn compression_algorithm(&self) -> Option<Compression>

Get the compression algorithm, if footer is compressed.

pub fn set_compression(&mut self, compression: Compression)

Set the compression algorithm (also sets the compressed flag).

pub fn clear_compression(&mut self)

Clear compression (footer is uncompressed).

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Header

impl Debug for Header

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

Formats the value using the given formatter.

impl Default for Header

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Header

impl PartialEq for Header

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