impl<'a, DATA: Read + Seek, const N: usize> FileChunkIterator<'a, DATA, N>

pub async fn next_chunk(&mut self) -> Result<Option<Vec<u8>>>

Returns the next chunk of data.

Returns Ok(Some(Vec<u8>)) with up to N bytes, Ok(None) at EOF.

pub fn total_size(&self) -> u64

Returns the total size of the file in bytes.

pub fn position(&self) -> u64

Returns the current position in the file (bytes read so far).
