Struct ChunkedFileBuffer 

pub struct ChunkedFileBuffer {
    pub storage: Vec<u8>,
    pub chunk_size: usize,
    pub read_pos: usize,
    pub write_pos: usize,
    pub bytes_written: usize,
}

Chunked file reader/writer that processes data in fixed-size blocks.

Suitable for large datasets that exceed available memory. Both reading and writing are abstracted as in-memory operations (no actual file I/O in this mock implementation).

Fields

storage: Vec<u8>

Underlying byte storage (simulates a file).

chunk_size: usize

Chunk size in bytes.

read_pos: usize

Current read position.

write_pos: usize

Current write position.

bytes_written: usize

Total bytes written.

Implementations

impl ChunkedFileBuffer

pub fn new(chunk_size: usize) -> Self

Create a new chunked buffer with the given chunk size.

pub fn write_chunk(&mut self, data: &[u8])

Write a chunk of data to the buffer.

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

Read the next chunk. Returns None if no more data.

pub fn available_chunks(&self) -> usize

Number of full chunks available for reading.

pub fn reset_read(&mut self)

Reset read cursor to beginning.

pub fn stored_bytes(&self) -> usize

Total bytes stored.

Trait Implementations

impl Debug for ChunkedFileBuffer

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

Formats the value using the given formatter.
