pub struct TileBuffer<const N: usize, R: AsyncRangeRead + 'static> { /* private fields */ }

TileBuffer structure

Implementations

impl<const N: usize, R: AsyncRangeRead> TileBuffer<N, R>

pub fn new(inner: R) -> Self

pub fn new_with_tile_size(inner: R, tile_size: usize) -> Self

pub fn new_with_tile_size_and_offset( inner: R, tile_size: usize, tile_pointer: usize, ) -> Self

pub fn set_offset(&mut self, new_offset: usize)

Set new offset calling that method will recalculate mappings, reuse already loaded tiles and stage the ones which not loaded

Trait Implementations

impl<const N: usize, R: AsyncRangeRead> AsyncRead for TileBuffer<N, R>

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut ReadBuf<'_>, ) -> Poll<Result<()>>

Attempts to read from the AsyncRead into buf.

impl<const N: usize, R: AsyncRangeRead> AsyncSeek for TileBuffer<N, R>

fn start_seek(self: Pin<&mut Self>, position: SeekFrom) -> Result<()>

Attempts to seek to an offset, in bytes, in a stream.

fn poll_complete( self: Pin<&mut Self>, _cx: &mut Context<'_>, ) -> Poll<Result<u64>>

Waits for a seek operation to complete.
