Struct Scirs2Writer 

pub struct Scirs2Writer<W: Write> { /* private fields */ }

Low-level writer for .scirs2 files.

Writes exactly one payload per instance. For multiple payloads use separate writers.

Example

use scirs2_core::serialization::{Scirs2Writer, PayloadType, CompressionType};
use std::fs::File;

let file = File::create("/tmp/out.scirs2").expect("should succeed");
let mut writer = Scirs2Writer::new(file);
writer
    .write_payload(PayloadType::Custom, b"hello scirs2", CompressionType::None)
    .expect("should succeed");

Implementations

impl<W: Write> Scirs2Writer<W>

pub fn new(writer: W) -> Self

Wrap an existing Write implementor.

pub fn write_payload( &mut self, payload_type: PayloadType, payload: &[u8], compression: CompressionType, ) -> Result<(), SerializationError>

Compress (if requested) and write a single payload to the underlying writer.

The CRC32 checksum is computed over the uncompressed payload bytes. The stored bytes (in the file, after the header) may be compressed.
