Struct ChunkedReader

pub struct ChunkedReader<F>
where
    F: FnMut(u64, &mut [u8]) -> Result<(), IsoError>,
{
    block_io: ChunkedBlockIo<F>,
    position: u64,
    sector_buf: [u8; 512],
}

Simpler read interface for when you just need byte-level access

Fields

block_io: ChunkedBlockIo<F>

position: u64

Current position

sector_buf: [u8; 512]

Sector buffer for unaligned reads

Implementations

impl<F> ChunkedReader<F>

where F: FnMut(u64, &mut [u8]) -> Result<(), IsoError>,

pub fn new(ctx: IsoReadContext, read_fn: F) -> Self

Create a new chunked reader

pub fn total_size(&self) -> u64

Get total size

pub fn position(&self) -> u64

Get current position

pub fn seek(&mut self, pos: u64) -> Result<(), IsoError>

Seek to position

pub fn read(&mut self, buffer: &mut [u8]) -> Result<usize, IsoError>

Read bytes at current position

pub fn read_exact(&mut self, buffer: &mut [u8]) -> Result<(), IsoError>

Read exact number of bytes (error if not available)
