Struct Scirs2Reader 

pub struct Scirs2Reader<R: Read + Seek> {
    pub header: Scirs2Header,
    /* private fields */
}

Low-level reader for .scirs2 files.

The header is parsed eagerly on construction; the payload bytes are read lazily on demand.

Example

use scirs2_core::serialization::Scirs2Reader;
use std::fs::File;
use std::io::BufReader;

let file = BufReader::new(File::open("/tmp/out.scirs2").expect("should succeed"));
let mut reader = Scirs2Reader::new(file).expect("should succeed");
println!("payload type = {:?}", reader.header.payload_type);
let bytes = reader.read_payload().expect("should succeed");

Fields

header: Scirs2Header

Header parsed from the beginning of the file.

Implementations

impl<R: Read + Seek> Scirs2Reader<R>

pub fn new(reader: R) -> Result<Self, SerializationError>

Open a .scirs2 reader, validating and parsing the header immediately.

Returns SerializationError::InvalidMagic when the file is not a valid .scirs2 file, or SerializationError::UnsupportedVersion when the format major version is newer than this library.

pub fn read_payload(&mut self) -> Result<Vec<u8>, SerializationError>

Read and decompress the payload, returning the raw (uncompressed) bytes.

This method seeks back to the start of the payload each time it is called, so repeated calls are safe.

pub fn verify_checksum(&mut self) -> Result<bool, SerializationError>

Read the payload and verify its CRC32 against the header checksum.

Returns Ok(true) if the checksum matches, Ok(false) otherwise. Returns Err on I/O or decompression failure.
