Struct MarkerHeaderParser 

pub struct MarkerHeaderParser;

Parser for the RAR archive marker (signature) header.

Implementations

impl MarkerHeaderParser

pub const HEADER_SIZE: usize = 7

Size of the RAR4 marker header in bytes.

pub fn detect_version(buffer: &[u8]) -> Result<RarVersion>

Detect RAR version from buffer without full parsing.

Returns RarVersion::Rar4 or RarVersion::Rar5 based on the signature bytes, or RarError::InvalidSignature if the buffer doesn’t start with a valid RAR signature.

use rar_stream::parsing::marker_header::MarkerHeaderParser;
use rar_stream::parsing::marker_header::RarVersion;

let rar4 = [0x52, 0x61, 0x72, 0x21, 0x1A, 0x07, 0x00];
assert_eq!(MarkerHeaderParser::detect_version(&rar4).unwrap(), RarVersion::Rar4);

let rar5 = [0x52, 0x61, 0x72, 0x21, 0x1A, 0x07, 0x01, 0x00];
assert_eq!(MarkerHeaderParser::detect_version(&rar5).unwrap(), RarVersion::Rar5);

assert!(MarkerHeaderParser::detect_version(b"not rar").is_err());

pub fn parse(buffer: &[u8]) -> Result<MarkerHeader>

Parse marker header from buffer. The marker header is actually parsed as a generic RAR header. The “size” field tells us how many bytes this header consumes.
