pub struct ReadCache<R: Read + Seek> { /* private fields */ }
Expand description

An implementation of ReadRef for data in a stream that implements Read + Seek.

Contains a cache of read-only blocks of data, allowing references to them to be returned. Entries in the cache are never removed. Entries are keyed on the offset and size of the read. Currently overlapping reads are considered separate reads.

Implementations

Create an empty ReadCache for the given stream.

Return an implementation of ReadRef that restricts reads to the given range of the stream.

Free buffers used by the cache.

Unwrap this ReadCache<R>, returning the underlying reader.
