Struct snap::Reader
[−]
[src]
pub struct Reader<R: Read> { // some fields omitted }
A reader for decompressing a Snappy stream.
This Reader
wraps any other reader that implements io::Read
. Bytes
read from this reader are decompressed using the
Snappy frame format
(file extension sz
, MIME type application/x-snappy-framed
).
This reader can potentially make many small reads from the underlying stream depending on its format, therefore, passing in a buffered reader may be beneficial.
