SnowBinary

A basic header based binary file format, writer and reader.

Basic Example

```rust { let info = SnowBinInfo::default();

let writer = SnowBinWriter::new(&info, PATH as PathBuf)?;
writer.write("Header", DATA as &[u8])?;

} // File is flushed when writer.close() is called or when writer is dropped.

{ let reader = SnowBinReader::new()?; reader.read("Header")?; // Returns data has Vec } ```

Binary Format (Supported by this version)

Spec 2

• Default Max Header Size: 8 bytes.

• Default Max Data Size: u64.

• Start with an 8 byte header of "SNOW_BIN".

• Then 8 bytes showing the snow binary version. (Spec Version) (u64)
• Then 4 bytes showing the max header size in bytes. (At least 8 bytes, max of u32::MAX bytes) (u32)
• Then 1 byte showing the max data size. (u8::MAX, u16::MAX, u32::MAX, u64::MAX) (u8)
• Then write data:
  • Header of MAXHEADERSIZE. (No conflicting header names. This is not checked by the writer or reader.)
  • Data size of MAXDATASIZE.
  • Data.
  • Repeat until \/.
• End with a MAXHEADERSIZE header of "SNOW_END".
• 32 byte verification hash. (Using blake3)
