Instance Method Summary

• #close

  Ends the current LZ4 frame, the stream can still be written to, unless @sync_close

• #closed? : Bool

  Returns true if this IO is closed.

• #compressed_bytes_in : UInt64
• #compressed_bytes_out : UInt64
• #finalize
• #flush : Nil

  Flush LZ4 lib buffers even if a block isn't full

• #local_address : Socket::Address
• #local_address=(local_address : Socket::Address)
• #local_address? : Socket::Address | Nil
• #read(slice : Bytes) : Int32

  Reads at most slice.size bytes from this IO into slice.

• #remote_address : Socket::Address
• #remote_address=(remote_address : Socket::Address)
• #remote_address? : Socket::Address | Nil
• #rewind

  Rewinds this IO.

• #sync_close=(sync_close : Bool)
• #sync_close? : Bool
• #uncompressed_bytes_in : UInt64
• #uncompressed_bytes_out : UInt64
• #write(slice : Bytes) : Nil

  Writes the contents of slice into this IO.
