class Compress::Zlib::Reader
Overview
A read-only IO
object to decompress data in the zlib format.
Instances of this class wrap another IO object. When you read from this instance instance, it reads data from the underlying IO, decompresses it, and returns it to the caller.
Included Modules

compress/zlib/reader.crConstructors
-
.new(io : IO, sync_close : Bool = false, dict : Bytes | Nil = nil)
Creates a new reader from the given io.
Class Method Summary
-
.open(io : IO, sync_close = false, dict : Bytes | Nil = nil, &)
Creates a new reader from the given io, yields it to the given block, and closes it at the end.
