Struct PrefetchReader 

Source 
pub struct PrefetchReader { /* private fields */ }
Expand description

An AsyncFileReader that caches the first prefetch bytes of a file.

Implementations§

Source§

impl PrefetchReader

Source

pub async fn new( reader: Box<dyn AsyncFileReader>, prefetch: u64, ) -> AsyncTiffResult<Self>

Construct a new PrefetchReader, catching the first prefetch bytes of the file.

Trait Implementations§

impl AsyncFileReader for PrefetchReader

Source§

fn get_bytes(&self, range: Range<u64>) -> BoxFuture<'_, AsyncTiffResult<Bytes>>

Retrieve the bytes in range
Source§

fn get_byte_ranges( &self, ranges: Vec<Range<u64>>, ) -> BoxFuture<'_, AsyncTiffResult<Vec<Bytes>>>
where Self: Send,

Retrieve multiple byte ranges. The default implementation will call get_bytes sequentially
