Struct SaveFile 

pub struct SaveFile {
    pub header: SaveHeader,
    pub snapshot: WorldSnapshot,
    pub checksum: u32,
}

A complete in-memory representation of a save file.

Call write_to_bytes() / write_to_file() to persist it.

Fields

header: SaveHeader

snapshot: WorldSnapshot

checksum: u32

CRC-32 checksum of header + snapshot bytes. Computed lazily on write.

Implementations

impl SaveFile

pub fn new(snapshot: WorldSnapshot) -> Self

pub fn with_header(self, header: SaveHeader) -> Self

pub fn write_to_bytes(&mut self) -> Vec<u8>

Serialize to a byte vector using the binary format described in the module doc.

pub fn write_to_file(&mut self, path: &str) -> Result<(), SaveError>

Write the save file to disk at path.

pub fn read_from_bytes(bytes: &[u8]) -> Result<SaveFile, SaveError>

Parse a SaveFile from raw bytes.

pub fn read_from_file(path: &str) -> Result<SaveFile, SaveError>

Read a SaveFile from a file on disk.

pub fn verify_checksum(&self) -> bool

Re-compute the checksum and compare it with the stored value.
