Struct ChunkedWriter 

pub struct ChunkedWriter {
    pub path: String,
    pub frame_count: usize,
    pub chunk_size: usize,
}

Streaming binary writer for large simulation data sets.

Each call to write_chunk appends a serialised SimulationChunk to the output file.

Fields

path: String

Path to the output file.

frame_count: usize

Number of frames written so far.

chunk_size: usize

Maximum particles per chunk (advisory; not enforced).

Implementations

impl ChunkedWriter

pub fn new(path: impl Into<String>, chunk_size: usize) -> Self

Create a new writer targeting path with advisory chunk_size.

pub fn write_chunk(&mut self, chunk: &SimulationChunk) -> Result<(), String>

Append chunk to the file.

Returns an error string on I/O failure.

pub fn frame_count(&self) -> usize

Number of frames written.

pub fn finalize(&mut self) -> Result<(), String>

Finalise the file (no-op in this implementation — flush is automatic).

Trait Implementations

impl Debug for ChunkedWriter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
